Answer

Brief Explanations:

During cellular respiration, the high - energy electrons in the electron transport chain come from NADH and FADH₂ which are produced in earlier stages like glycolysis, the citric acid cycle. NAD⁺ and FAD are the oxidized forms that get reduced to carry electrons. Glucose is the starting molecule of cellular respiration but the electrons are transferred to NAD⁺ and FAD to form NADH and FADH₂ first. Water is a product of the electron transport chain.

Answer:

B. NADH and FADH₂
