Question

The end product of oxidative phosphorylation is

• A. Oxygen
• B. $ATP+H_{2}O$
• C. $ADP$
• D. $NADH$

Answer 1

The correct option is B

$ATP+H_{2}O$

Oxidative phosphorylation

● Oxidative phosphorylation is the process of ATP synthesis by oxidation reduction reactions.

● In mitochondria, oxygen acts as a final electron acceptor and reacts with protons to form water.

● The proton gradient formed across the inner mitochondrial membrane helps in the ATP synthesis.

● Thus, the final products of oxidative phosphorylation are water and ATP.

Final answer:

d) $ATP+H_{2}O$
