Which of the following events takes place in the electron transport chain?
A) the breakdown of glucose into six carbon dioxide molecules
B) the breakdown of an acetyl group to carbon dioxide
C) the harnessing of energy from redox reactions to generate a proton gradient
D) substrate-level phosphorylation

Question

Quizplus · Accepted Answer

The electron transport chain harnesses energy from redox reactions to generate a proton gradient across the mitochondrial membrane, which is then used to produce ATP. This process does not directly involve the breakdown of glucose or acetyl groups, nor does it involve substrate-level phosphorylation.
