During aerobic respiration, the passing on of the electrons removed as a part of the hydrogen atom to molecular O 2 occurs in the __________.
Options
- ACytoplasm
- BMitochondrial outer membrane
- CMitochondrial inner membrane
- DMitochondrial matrix
Correct answer
C. Mitochondrial inner membrane
Step-by-step solution
Mechanism of ATP production : When the electrons pass from one electron carrier to another carrier (from complex I to IV) in ETS, they are coupled to ATP synthase (complex V) and thus ATP are synthesized. Molecule oxidized in ETS Number of ATP produced 1 molecule of NADH 3 ATP 1 molecule of FADH 2 2 ATP Role of O 2 : The role of oxygen is limited to the terminal stage of the aerobic process but is vital - it acts as the final hydrogen acceptor and it drives the whole process by removing H+ from the system.
