Question

Process of photophosphorylation was first given by

• A. Hill
• B. Willstatter and Stoll
• C. Arnon
• D. Park

Answer 1

The correct option is C Arnon

Photophosphorylation is synthesis of ATP from ADP in presence of light in the chloroplast. It is also called as photosynthetic phosphorylation. It was discovered by Arnon in 1954. Arnon gave difference between two types of photophosphorylation, cyclic and non-cyclic photophosphorylation. He gave resemblance of photophosphorylation with oxidative phosphorylation. The difference between the two is in photophosphorylation ATP is synthesized using light energy whereas in oxidative phosphorylation, ATP is synthesized using chemical energy.

Thus, the correct answer is option C.
