Which of the pathways below are in the correct order for the flow of electrons from glucose to oxygen in aerobic respiration?

Question

Quizplus · Accepted Answer

The correct order for the flow of electrons from glucose to oxygen in aerobic respiration is glycolysis, TCA, and ETS. Glycolysis occurs in the cytoplasm, TCA occurs in the mitochondrial matrix, and ETS occurs in the inner mitochondrial membrane. Fermentation is not a part of aerobic respiration and does not involve the use of oxygen. Choice A is a possible sequence but in the reverse order. Choice C is not correct as TCA (also known as the citric acid cycle) must occur before ETS (electron transport system).
