During the third stage of aerobic respiration, electrons and hydrogen ions released by the reactions of the first two stages are picked up by A) photosynthetic enzymes and ATP. B) CO₂and H₂O C) iron and glucose. D) NAD+ and FAD. E) none of these.

Question

Quizplus · Accepted Answer

During the third stage of aerobic respiration, electrons and hydrogen ions are picked up by electron carriers such as NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). These carriers will transport the electrons to the electron transport chain, which will eventually result in the production of ATP. Option A is incorrect because photosynthetic enzymes are not involved in aerobic respiration. Option B is incorrect because CO₂and H₂O are not relevant to the third stage of aerobic respiration. Option C is incorrect because iron is not an electron carrier and glucose is not involved in the third stage of aerobic respiration.
