Glyceraldehyde-3-phosphate dehydrogenase catalyzes the phosphorylation of glyceraldehyde-3-phosphate, but unlike other glycolytic reactions, it does not require energy investment from ATP. This reaction occurs in two stages: oxidation/reduction and phosphorylation.

Why is the oxidation/reduction reaction necessary to make phosphorylation favorable?

A. The oxidation/reduction reaction is necessary to oxidize phosphate, allowing addition to the substrate. B. The oxidation/reduction reaction is necessary to form an intermediate with a large free energy of hydrolysis. C. The oxidation/reduction reaction is necessary to produce NADH, which is required for ATP synthesis. D. The oxidation/reduction reaction is for the substrate to bind to the enzyme.
