Question

Which one respiratory complex is coupled with ETS for ATP synthesis?

• A. Complex I
• B. Complex III
• C. Complex IV
• D. Complex V

Answer 1

Answer: (D)

Complex V

ATP synthase is also called complex V. It is the final enzyme in the oxidative phosphorylation pathway and utilizes the energy stored in a proton gradient across a membrane to drive the synthesis of ATP from ADP and phosphate (Pi).

So, the correct option is 'Complex V'.
