Question

Match the enzyme-catalyzed reaction to the cofactor that makes up part of the "swinging arm" or tether that is involved in the reaction. The choices may be used more than once or not at all. Choose between beta-mercaptoethylamine and pantothenate, biotin, none of the indicated cofactors, lipoate, or pyridoxal phosphate for each of the following:

Pyruvate carboxylase

Pyruvate decarboxylase

E2 of the pyruvate dehydrogenase complex

E2 of the alpha-ketoglutarate complex

Acyl carrier protein of fatty acid synthase

Acetyl-CoA carboxylase

Phosphoenolpyruvate carboxylase
