Question

What is/are the energy storage molecules that are generated during cellular respiration? How many are generated for every one glucose molecule? Explain why physiological processes are never quite entirely efficient; how would this impact the theoretical energy yield?

Answer 1

Ans) The energy storage molecules that are generated during cellular respiration are ATP(adenosine triphosphate) .

One molecule of glucose during aerobic respiration in eukaryotes generates 38 molecules of ATP.

Physiological processes are never quiet entirely efficient.Determining the exact yield of ATP for aerobic respiration is difficult for a number of reasons. Proton motive force are used to generate ATP molecules and it is also used for functions such as transporting materials across membranes and rotating flagella. Some bacteria use different carriers in their electron transport chain than others and the carriers may vary in the number of protons they transport across the membrane which then makes the yield of ATP different. Furthermore, the number of ATP generated per reduced NADH or FADH2 is not always a whole number.This in turn impacts the theoretical energy yield of ATP.
