Question

ATP formation during photosynthesis is known as

• A. Phosphorylation.
• B. Photophosphorylation.
• C. Oxidative phosphorylation.
• D. Substrate level phosphorylation.

Answer 1

Answer: (B)

Photophosphorylation.

Photophosphorylation refers to the use of light energy from photosynthesis to ultimately provide the energy to convert ADP to ATP, thus replenishing the universal energy currency in living things. Light generally provides energy to form the bonds. It is an endothermic reaction.

So, the correct answer is option B.
