Aerobic Respiration Involves the Transfer of Many Electrons from Glucose

question 12

Multiple Choice

Aerobic respiration involves the transfer of many electrons from glucose to electron carriers such as NAD⁺ over a series of multiple steps.Ultimately though,it is the reaction of glucose with oxygen to generate carbon dioxide,water and energy.Why doesn't glucose react directly with oxygen in cells?

• A)Oxygen cannot accept electrons,and thus an electron carrier like NAD⁺ is needed.
• B)Oxygen and glucose are localized in different subcellular compartments.
• C)The direct reaction of oxygen with glucose would be extremely destructive to cells.
• D)The reaction of oxygen with glucose is not spontaneous.
