Answer:
Explanation:
Oxidative phosphorylation is the process  through which ATP is produced by the transfer of electrons from NADH or FADH 2 to O₂ by a series of electron carriers. This process, occurs in mitochondria, in aerobic organisms.
In the absence of Oâ‚‚ (anaerobic condition), both electron transport and ATP synthesis would stop because the Oâ‚‚ is the final electron acceptor in oxidative phosphorylation, if Oâ‚‚ Â is not present then the electron acceptor is changed.
