Question

ATP molecules, which are used for energy by cells, are built during all three stages of cellular respiration. Which stage of cellular respiration generates the most ATP molecules? The Krebs cycle O Glycolysis O The electron transport chain O Fermentation OThe electron transport chain

Answer 1

THE ELECTRON TRANSPORT CHAIN GENERATES THE HIGHEST NUMBER OF ATP. The electron transport chain produce 34 ATP molecules. The principal function of electron transport chain is to regenerate electron carriers and to make proton gradient. In glycolysis and fermentation processes, only 2 ATP are generated.
