One of the Ways That Cells Balance Anabolism and Catabolism

One of the ways that cells balance anabolism and catabolism is to

A) use separate coenzymes such as NAD+ vs. NADP+ for catabolic vs. anabolic pathways.
B) use the same enzyme to run a reaction in both the catabolic and anabolic direction and use feedback inhibition to shut down a pathway that is not needed.
C) use feedback inhibition to shut down a pathway that is not needed and use separate coenzymes such as NAD+ vs. NADP+ for catabolic vs. anabolic pathways.
D) use feedback inhibition to shut down a pathway that is not needed.
E) use the same enzyme to run a reaction in both the catabolic and anabolic direction.
