As enzymes normally only catalyse one reaction the substrate has to fit in the specific shape (active site) and if it doesn’t fit in (lock and key method) then the enzyme won’t be catalysed. b.) As when the enzyme is denatured it’s special shape is destroyed, thus destroying it’s active site meaning that the substrate wont be able to fit in, therefore not catalysing the enzyme. c.) As enzymes are specific when an enzyme catalyses an enzyme it can be used over and over again as they are not changed during the reaction. 5.) a.) if the concentration of the enzyme is increased the rate f the reaction will increase.

Jane Austens Life and Work Essay -- Author Biography

Jane Austen, one of the most celebrated novelists, wrote seven of the most distinguished novels in the English language. Her first novel--which she started in 1795, revised in 1809 or 1810, and finally published in 1811—was Sense and Sensibility. Many agree that her most renowned work would be Pride and Prejudice. Austen began writing in her early twenties but did not publish her work until later in her life. She obtained a better education than most women of her time. Born in Steventon Village in Hampshire on December 16, 1775, Austen was born into an upper middle class family. She was the daughter of George Austen, a clergyman, and Cassandra Austen. Austen received her education at Reading Abby School. Before she was eighteen Austen had written three volumes of juvenilia and her first book was published at the age of thirty-five. Pride and Prejudice, originally titled First Impressions, was submitted to a London publisher by her father in 1797, a year after Austen b egan writing it. Although the novel was enjoyed by many of her friends and family, the publisher rejected it. She moved to Bath in 1801 and continued to work on First Impressions until 1805 when her father and a close friend passed away in which time she stopped writing for almost five years. In 1809 Austen moved to Hampshire at Chawton College, close to her hometown of Steventon and on January 28, 1813 Pride and Prejudice was published anonymously. Austen’s novels are about people of her societal class on courtship and marriage and throughout her life there were approximately fifteen anonymous reviews, three on Pride and Prejudice. James Edward Austen-Leigh, Austen’s nephew, wrote her first biography in 1870 portraying her as a benevolent, devout, â€Å"spin... ...te, clever, pointed, and satirical to say the least. Jane Austen’s Emma relates to her life in the fact that she writes about the people in her societal class. All of her characters live near the area she grew up in and are all upper middle class families. In Emma George Knightley is often the voice of Austen herself. He relays her opinions and emotions in a subtle way that does not disengage the reader too much. While relaying her opinions and emotions through a character within the novel, it keeps the reader involved enough to keep their emotions within the story and not towards Austen herself.

Classical music Essay

It is Saturday March 1 2008 and I have woken with an excited feeling in my stomach. Today, I am being treated to something I have never experienced before and I am looking forward to what is in store. My father, is taking me to a classical concert. I am 18 years old and big band music is not really my style, I appreciate music but of the modern variety rather than the old school kind. My father loves classical music and plays it constantly in his study. His favourite composer is Leonard Bernstein so it is today, with great animation, he is taking me to encounter his love of this music. We are attending the Waukegan Concert Chorus which is at 624 Douglas Ave, Illinois, the concert is a tribute to Bernstein & Williams; namely, In Remembrance of Bernstein & Williams. My father assures me that although my liking of music may not be to his taste, I will go away from the concert feeling uplifted and appreciative of what I have heard. Our journey takes us to Waukegan during the early evening and as we approach the venue I can feel a buzz in the air. Other attendees are heading towards the seating area and as my father and I locate where we are sitting, I am somewhat satisfied that we have seats near to the front. My father explained in the car, on the way, even though it is the music you are listening to, it is also just as important to watch the performance. Before me is a huge orchestra; perhaps the biggest I have ever seen, not that I have seen many. There is a plethora of various noises coming from the ensemble and as each musician tunes in their instrument and plays small excerpts from their music stand, it is perhaps unbelievable that any kind of harmony will occur at all. However, the moment the conductor enters the room, there is an eerie silence, almost as if someone had turned the musicians off by a control button. The conductor is a gentleman who turns to his audience and bows his head, turning and repeating this gesture to his orchestra. As the first piece of music is played I feel myself vibrating with the enormity of the noise. For many years I have heard my father’s classical records being played from behind the study door but to be present at a live performance was truly exhilarating. One of my favourites in terms of familiarity was West Side Story. The introduction sounded amazing; upbeat and vibrant, the instruments seemed almost alive. Even closing my eyes, which I actually did, I could hear each piece of equipment as it was used. The brass and woodwind instrumentalists brought intrigue and manoeuvre to the story of the piece being played whilst the drums added the extra element of spirit in the arrangement. Despite the variety of instruments played and the different roles they played within the piece, the unity came together with such an intensity, I was taken aback by its impact. The formation and structure of the concert allowed me to lose myself within the music, it was almost as if I were watching the musical itself. This perhaps was the purpose of the concert itself, it worked with an effortless outcome. As the flutes and violins played ‘I Feel Pretty’, I felt almost compelled to stand up and sing as the notes poured through the air. The tempo was light in places and amplified in others; the exaggeration of drama was as apparent as the subtlety of tenderness applied to the nature of the story. Its volume was deafening yet tolerable as each instrument alerted itself naturally within the composition. On occasion I did look around at other spectators, like moths to a flame, transfixed faces and total satisfaction and appreciation of what was before and around them. I did relate to this. As the concert came to an end, I did feel somewhat saddened that it was all over. The climax of the music was a crescendo of brilliance and I am pleased to say, my father’s original prediction of how I would feel, was absolutely correct. I felt euphoric and inspired by such a performance. I had attended the concert with an open mind and allowed myself to absorb the instruments intentions; I felt all the raw emotions of West Side Story and even the pieces of music played I had heard for the first time, still brought me a sense of appreciation.

Has a Second Reformation Occured - 1914 Words

Throughout history many events have contributed in shaping our theology. Many would argue the rank of importance of each event. Obviously Jesus death, burial, and resurrection would top the list of most Christians. Many would place the Reformation next in line of importance, but what next? Has there been an event since the Reformation that would rise to the level of a Second Reformation? Could any event ever rival the salvific implications of the Reformation? And what criteria could one ascertain from the Reformation and could these same criteria be applied to a Second Reformation? These are the questions that beg to be answered. A large majority of Christians would tell you that the Reformation was one of the major events to occur in shaping our belief system as Protestants. Martin Luther and his God given revelation of justification through faith is the bedrock of twenty first century Christian though. It is impossible to believe that for hundreds of years Christianity was dominate d by a political and ecclesiastical dominance, to the extent that even the basics of our faith, such as salvation, was twisted and skewed into a bargaining tool for financial gain or power. However, God in his grace, revealed himself to a humble monk in Germany, who was hungry for revelation. By the voice and boldness of Martin Luther, we now have a basis for our salvation. Luther took us back to the original teachings of Jesus, back to salvation.

Rationally thinking, if minimum wage increases there will be more harm than good. Mark Caleb Smith, director of the Center for Political Studies at Cedarville University, stated that Increasing the minimum wage will have the short-term positive impact on people at the lower end of the wage scale., and his evaluation of the situation is well-interpreted. Raising minimum wages will bring short-term appeal to low-income workers, until they must be laid off or fired because businesses cannot afford to employ as many employees. Don’t waste time! Our writers will create an original "Minimum Wage Increases" essay for you Create order This will affect markets and have an impact on the supply, demand, and surplus of a specific market. Businesses will move away from hiring more workers towards robots, machines, and automated systems. Many businesses like fast food restaurants, supply lines, grocery stores, and many clothing stores have already incorporated robots into their business as a, so to say, replacement for human workers. This brings concerns that businesses may avoid hiring as many workers, especially teenagers, formerly incarcerated and other lower-skilled workers who usually have a difficult time getting jobs. According to a prediction made by a recent Congressional Budget Office report, an increase of the set minimum wage could result in a loss of jobs in the United States which will increase the number of unemployed and not employed. If minimum wage increases, meaning businesses had to pay more for labor, business owners would think to either; raise prices, cut costs or lower their profit margins. There is a motive that they will have more incentives to automate jobs. Research shows the number of entry level jobs in the market will be decreased if minimum wage is raised, and that is bad for teenagers, previously incarcerated and those with lower levels of education. In 2018, most jobs require some form of degree making those who did not attain a college education have to attain a low paying job. According to Huppke (2014), instead of raising the minimum wage, The better approach, according to minimum wage hike opponents, is to put money into education and job preparedness plans, which they say have proven success records. This graph shows how the market will be affected. It can interpret unemployment and those who are in the workforce. Because different states have different standards of livings, raising minimum wages could make a specific state less competitive. A wage of $15 in Georgia is much different to a $15 wage in California. Because of this, graphs of different states will be different and have a different outlook of their market, compared to another state. Some states minimum wages are determined by their inflation, which corresponds to their standard of living. Since minimum wages are determined by standards of living, some states who have increased their standard of living only truly have about $0.25-$1.00 more than the federally set wage. Overall, if the minimum wage increases or decreases the labor market is affected no matter which state.

How Technology Is Becoming More Widespread - 1197 Words

These days technology is becoming more widespread. The question is are we still reading as attentively and thoroughly as we used to due to these new portable ways of reading. The main issue here is that our attention is divided between pixels and link as our brains respond differently to onscreen text than to words on paper. There have been many published studies since 1980’s where researchers from different fields like psychology, computer engineering and information science have brought up such issues in more than one hundred published studies. Many of these studies done before 1992, always concluded that people read slowly, less accurately and less comprehensively on screens than on paper. In recent studies, it shows that people still like to read from paper especially when they want to read intensively. Although the e-reading technology is gaining more popularity and becoming more common, people’s attitudes are changing. They read these books for facts and fun. In the US, there is about 15 to 20 percent of all trade book sales (Jabr, 2013). People are known to be less conducive to learning from computers and tablets as compared to paper. Reading has a physicality. When we already have an e-book we start to miss it. There was a study done in January 2013 by Anne Mangen of the University of Stavanger in Norway.
