QUESTION 1 True or False: Metabolism is a controlled set of biochemical reactions that occur in living organisms in order to maintain life. TRUE QUESTION 2 True or False: Enzymes slow down chemic... al reactions to conserve energy. FALSE Enzyme catalyze (speed up) chemical reactions. QUESTION 3 What is a cofactor? And give a general example. A cofactor is a small chemical component that assists an enzyme during the catalysis reactions. A cofactor is usually metal ions. QUESTION 4 Define anabolism. Anabolism is the process of building up or biosynthesis of macromolecules from small molecular units into much larger complexes. QUESTION 5 In order to convert proteins into amino acids which metabolic process would be active? Catabolism would be active as proteins are made up of amino acids. Therefore the process described (proteins into amino acids) is the breakdown, or catabolism of protein. QUESTION 6 Describe the energy transfer process relative to both ATP and ADP ATP has the energy (phosphate group) to donate while ADP can accept energy in the form of a phosphate group. Thus, ATP can be reduced (ATP ⟶ADP + Pi) while ADP can be built into ATP (ADP + Pi ⟶ATP). [Show More]
