Question

The electron transport chain includes

• A. Photooxidation
• B. Cyclic phosphorylation
• C. Non-cyclic phosphorylation
• D. Oxidative phosphorylation

Answer 1

The correct option is D Oxidative phosphorylation

Oxidative phosphorylation refers to the synthesis of ATP by ADP and Pi driven by energy released from the oxidation of reducing powers NADH and FAD by transfer of their electrons through electron transport chain to oxygen. It is also called as electron transport chain. Cyclic phosphorylation and noncyclic phosphorylation are two types of phosphorylation wherein energy of photon drives ATP synthesis in the chloroplast. Photooxidation is sunlight driven oxidation.
