Question

How do high-energy electrons from glycolysis and the Krebs cycle contribute to the formation of ATP from ADP in the electron transport chain? A. High-energy electrons interact with pyruvic acid to create a phosphate bond with ADP, forming ATP. B. High-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. C. High-energy electrons supply a negative charge which causes the citric acid to oxidize, forming a phosphate group to bond with ADP. D. High-energy electrons increase the temperature of ADP so it easily reacts to form ATP.

Answer 1

The correct answer is option C.

The high energy molecules like FADH2 and NADH molecules provides electron and causes oxidative phosphorylation to generate more high-energy ATP molecules
