Which of the Following Events Takes Place in the Electron

Question

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

Accepted Answer

The electron transport chain is responsible for extracting energy from high-energy electrons remaining from glycolysis and the citric acid cycle. This energy is then used to create a proton gradient, which powers ATP synthesis through oxidative phosphorylation. The breakdown of glucose into pyruvate occurs during glycolysis, the breakdown of an acetyl group to carbon dioxide occurs during the citric acid cycle, substrate-level phosphorylation involves directly transferring a phosphate group to ADP to form ATP, and reduction of ADP to ATP can occur through various processes, with oxidative phosphorylation being one of them.
