The step in cellular respiration that produces the most ATP is the Electron Transport Chain.

Did you know?

Did you know that the step in cellular respiration that produces the most ATP is the electron transport chain? While both glycolysis and the Krebs cycle contribute to ATP production, it is the electron transport chain that generates the largest amount of ATP. This multi-step process occurs within the mitochondria and involves the transfer of electrons from electron carriers, such as NADH and FADH2, to the protein complexes located in the inner mitochondrial membrane. As the electrons pass through these complexes, the energy released is used to pump protons across the membrane, creating a proton gradient. This gradient drives ATP synthesis by powering the ATP synthase enzyme, resulting in the production of a whopping 32-34 molecules of ATP per one glucose molecule. So, the electron transport chain is the powerhouse of cellular respiration, generating the majority of ATP in the process.
