Biology Questions and Answers Essay 2.) a) proteins b.) i) Amylase ii) Protease iii) Lipase c) i) Glucose ii) Amino Acids iii) Fatty acids and Glycerol 3.) a.) Each enzyme has a unique shape that fits onto the substrate. 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. This is because there will be more enzymes to help break down the substrate, however when the enzyme reaches it’s optimum it will be equal. b.) if the temperature is decreased it will drop the rate of reaction and slow down the speed of catalysing. c.) if the pH is lowered then the rate of reaction will drop causing the pH to interfere with the bonds holding the enzyme together and denaturing the enzyme. 7.) a.) i) the rate of reaction is increasing at a positive constant correlation, because the increase in temperature is causing the enzymes to move around faster increasing the chance of a collision. ii) the rate suddenly drops after it’s hit the optimum temperature, this is because the bonds holding the enzyme together have broke destroying enzymes special shape. b.) It increases it as it causes the enzymes to move around faster increasing the chance of a collision. c.) the bonds change it’s special shape causing it unable to catalyse substances. d.) A. it could be pepsin in the stomach e.) B, it could be phosphatases f.) it is very narrow.

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.
