Answer :
Answer:
Water
Explanation:
- The electron transport chain is the third and the last phase of aerobic cellular respiration in living organisms.
- During the electron transport chain, electron carriers NADH and FADH₂ are used to generate energy in the form of ATP.
- During this phase, energy is generated through oxidative phosphorylation in the inner membrane of the mitochondrion.
- In the electron transport chain, hydrogen ions are transferred from NADH and FADH₂ and ultimately end up as part of water.
