The Kinetics of α-Chymotrypsin Introduction Chymotrypsin is a protease which cleaves proteins by a hydrolysis reaction‚ it does this by adding a molecule of water to a peptide bond. Although the hydrolysis reaction is thermodynamically favoured in the absence of a catalyst the half-life for a typical hydrolysis reaction by a protease is between 10 and 100 years‚ needless to say it is extremely slow1. Though this is true peptide bonds are hydrolysed within milliseconds in the body in the presence

AP Biology Lab: Catalase (Enzymes) Abstract In this laboratory exercise‚ studies of enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme

essential carbohydrates needed for athletes‚ and the effects of consuming carbohydrates before and during competition is very important in helping with the enhancing of an athlete’s endurance and his or her exercise performance. It is critical for athletes to ingest a significant amount of carbohydrates in their bodies in order to compete at high performance levels. Carbohydrates are the main fuel source for our body‚ but as athletes we must know the difference between good and bad carbohydrates. Good

Analysis: Which sample do you suspect has diabetes mellitus? Provide your reasons. Diabetes mellitus is a condition created by the inadequate secretion of insulin from the pancreas. Insulin is a hormone that allows your body to use carbohydrates or store them for future use. Inadequate amounts of insulin causes a condition called hyperglycemia‚ which is an excessive amount of glucose in the blood stream. When the blood is filtered through the kidney‚ a large of amount of glucose is retained in the

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water
