Question

Light reaction of photosynthesis is also called

• A. Calvin cycle
• B. Hill reaction
• C. TCA cycle
• D. All of the above

Answer 1

Answer: (B)

Hill reaction

The Hill reaction implies that the light-dependent reaction of photosynthesis is a result of a series of redox reactions and a suitable terminal electron acceptor is required for that reaction to occur. Hence, solar energy is converted to chemical energy by the reduction of NADP to NADPH.

So, the correct option is 'Hill reaction'.
