The formation of ATP by oxidative phosphorylation takes place in ____.
Options
- AGlycolysis
- BKrebs cycle
- CETS
- DFermentation
Correct answer
C. ETS
Step-by-step solution
Oxidative phosphorylation is the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH₂ to O₂ by a series of electron carriers. This process takes place in the Electron Transport System (ETS) located in the inner mitochondrial membrane. In glycolysis and the Krebs cycle, ATP is formed through substrate-level phosphorylation. Fermentation is an anaerobic process that does not involve oxidative phosphorylation. Answer: ETS
