Match the following coenzymes with their functions in enzyme catalyzed reactions

Question

Match the following coenzymes with their functions in enzyme catalyzed reactions. Coenzyme Functions TPP CoASH Biotin Lipoate FAD NADP A. activate acyl groups B. transfer acetaldehyde groups from one active site to another C. electron carrier always associated with a protein D. electron carrier E. activate and carry acetaldehyde groups F. CO_2 carrier In the figure below, write out the three possible fates of pyruvate produced from glycolysis. Make sure to include all of the products produced for each of the three reactions shown below. Indicate the enzyme that carries out each reaction and whether the reaction will occur in the presence or absence of oxygen.

Explanation / Answer
