Question

Which of the following best describes the function of NAD+ and FAD in catabolic pathways?

competitive inhibitors of the enzymes present in each pathway

oxidizing agents that accept electrons and hydrogen ions from compounds undergoing oxidation

non-competitive inhibitors of the enzymes present in each pathway

transport molecules that carry two-carbon acetyl units to or from the different pathways

enzymes that catalyze the hydrolysis of ATP

competitive inhibitors of the enzymes present in each pathway

oxidizing agents that accept electrons and hydrogen ions from compounds undergoing oxidation

non-competitive inhibitors of the enzymes present in each pathway

transport molecules that carry two-carbon acetyl units to or from the different pathways

enzymes that catalyze the hydrolysis of ATP

These coenzymes (NAD and FAD) pass atoms and their electrons to compounds in the chain .

In general, catabolic reactions transform raw materials into:

1.) precursor molecules, 2.) ATP, 3.) reducing power (NADH, FADH2)Answer is (b.) because these two are oxidising agents
