Question

The process of photosynthetic photophosphorylation was described by

• A. Blackman
• B. Hill
• C. Arnon
• D. Benson

Answer 1

The correct option is C Arnon

• F.F. Blackman, a British plant physiologist discovered that photosynthesis is a two-step process and only one of which uses light directly.
• Hill discovered that green particles obtained from broken cells could produce oxygen from water in the presence of light and a chemical compound, such as ferric oxalate, able to serve as an electron acceptor. This process is known as Hill reaction.
• Benson was the co-researcher of Calvin who discovered the Calvin cycle in photosynthesis.
• The process of photosynthetic photophosphorylation was discovered by Arnon. Photosynthetic photophosphorylation is the process of phosphate group transfer into ADP to synthesize energy-rich ATP molecules making use of light as an external energy source. So, this option is correct.
