Question

Phosphorylation in mitochondria and chloroplast differ on the basis of requirement of : -

• A. A membrane
• B. ATPase
• C. Proton gradient
• D. Light

Answer 1

The correct option is A A membrane

Photophosphorylation is the process of light-driven synthesis of energy ATP. they occur in both chloroplasts and mitochondria. Photophosphorylation in mitochondria is called oxidative phosphorylation and occurs across the membrane of mitochondria and forms a potential gradient. In chloroplast phosphorylation, it is called photophosphorylation, it is light dependent and produces energy, a membrane is not present here.

So, the correct option is 'A membrane'.
