Question

Which option is not correct for chemiosmotic theory?

• A. ATP synthesis is linked with proton gradient
• B. Break down of proton gradient releases energy
• C. ATPase enzyme act as pump to break proton gradient
• D. It is applicable for photo phosphorylation and oxidative phosphorylation

Answer 1

The correct option is C ATPase enzyme act as pump to break proton gradient

• There is a proton gradient created across the thylakoid membrane. The breakdown of this gradient is important because it leads to the release of energy. The gradient is broken down due to the movement of protons across the membrane to the stroma through the transmembrane channel ADP ATP of the F0 of the ATPase.
• The ATPase enzyme consists of two parts: F0 and F1. This breakdown provides enough energy to cause a conformational change in the F1 particle of the ATPase, which makes the enzyme synthesize ATP.

So, the correct option is 'ATPase enzyme act as a pump to break proton gradient'.
