Which reactions both require energy?

Question

Quizplus · Accepted Answer

ATP production and the reduction of NAD+ (or similar compounds) both require energy input. ATP production involves synthesizing ATP from ADP and phosphate, which requires energy, typically from the breakdown of glucose or other substrates in cellular respiration or photosynthesis. The reduction of NAD+ to NADH also requires energy, as it involves adding electrons (and usually a proton) to NAD+, which is often coupled with energy-releasing reactions like the breakdown of glucose in glycolysis or the citric acid cycle.
