Which process results in the greatest atp output? (1 point)
(a)krebs cycle
(b)pyruvate oxidation
(c)glycolysis
(d)electron transport chain

The answer is electron transport chain. It is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples the electron transfer with the transfer of protons across a membrane. Electrons are transferred from NADH and FADH2 (proton donors) through the electron chain to oxygen, which is reduced to water. This process produces 34 ATP molecules and water from the carrier molecules.
