Question

Which is end product of oxidative phosphorylation?

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

Answer 1

The correct option is B ATP + $H_{2}O$

the process produces the 2 pyruvate molecule with 2 water molecule, 2 ATP, 2 NADH molecules, and 2 hydrogen ions. At the end of electron transport, oxygen is the final electron acceptor, and it combines also with hydrogen ions to form H2O. The end product of oxidative phosphorylation would be ATP molecules, which carry energy.

So the correct option is 'ATP + H${}_2$O'.
