The energy yield from the breakdown of a single molecule of glucose does not depend upon

Question

Quizplus · Accepted Answer

The energy yield from the breakdown of a single molecule of glucose is determined by the process of cellular respiration, which involves glycolysis, the Krebs cycle, and oxidative phosphorylation. The supply of carbon dioxide does not play a significant role in this process, and therefore, the energy yield from glucose breakdown does not depend on it. The other options do affect the energy yield: A) whether the NADH produced in glycolysis passes its electrons across the mitochondrial membrane to NAD+ or FAD affects the ATP yield from oxidative phosphorylation; B) the supply of oxygen affects the oxidative phosphorylation step, which is where the majority of ATP is produced; and D) the use of the H+ gradient for work other than ATP production would reduce the energy yield.
