Thank you so much!

Also, is it true that NADH oxidation requires oxygen reduction?

What are your thoughts on these two questions? I'll give you a frame of reference for your first question: consider what would happen chemically to convert chymotrypsinogen into chymotrypsin. With respect to your second question, can you think of any reactions that require NADH as a reactant?

Think about reactions from glycolysis/gluconeogenesis that produce or consume NADH. Also there are at least three common fates of pyruvate that has been produced from glycolysis. Do any of these processes involve NADH?
