Abstract This experiment investigated the kinetics of the enzyme glycogen phosphorylase b which is important to metabolism. AMP is an allosteric activator of the enzyme because it converts glycogen phosphorylase b from its T state to the R state which is the active form. Caffeine is an inhibitor because it binds the nucleoside inhibitor site. When it binds this site‚ it stabilizes the inactive T state and blocks the catalytic site which needs to be open for enzyme activity to occur. The glycogen

How the structure of proteins are related to their functions Rachel Morris The basic building blocks of proteins are amino acids‚ the biuret reaction tests for protein. A solution of sodium hydroxide is added to a sample then a few drops of copper sulphate solution‚ if positive – the solution will turn mauve. There are 20 different amino acids and they can be joined in any order. Therefore there can be many different functions. A protein consists of one or more polypeptide chains (a polypeptide

INTRODUCTION These polymers composed of amino acid monomers called proteins are important to our body. Protein is important because it composes parts of our body and assists in bodily functions. A type of protein named keratin makes up our hair and nails. Protein is used in your body to repair and build tissue‚ and it is a necessity in making hormones‚ enzymes‚ and other chemicals in the body. Many people use protein substances and supplements in correlation with weight lifting and working out to

The Central Role of the Citric Acid Cycle 3 processes play central roles in aerobic metabolism. The citric acid cycle. Electron transport . Oxidative phosphorylation. Metabolism consists of: Catabolism: the oxidative breakdown of nutrients. Anabolism: the reductive synthesis of biomolecules. • The citric acid cycle is amphibolic that is‚ it plays a role in both

are used up before lipids with carbohydrates being predominantly used at the 5min mark and lipids being mainly used at the 45min mark. This may be due to the fact that carbohydrates compared to fatty acids can be more readily converted since the metabolism process is much simpler. Carbohydrates do not have to be transported to the muscle cells since they are already present within the cells themselves while fatty acids are not. Fatty acids also require many additional processes for them to enter the
