Which of the following events takes place in the electron transport chain?
A) the breakdown of an acetyl group to carbon dioxide
B) breakdown of glucose into two pyruvate molecules
C) substrate- level phosphorylation
D) the extraction of energy from high- energy electrons remaining from glycolysis and the Krebs cycle

Question

Quizplus · Accepted Answer

The electron transport chain is responsible for extracting energy from high-energy electrons remaining from glycolysis and the Krebs cycle, which are carried by electron carriers such as NADH and FADH2. This energy is used to generate ATP. A, B, and C are all processes that occur prior to the electron transport chain.
