Question

1.6) In comparing the light reaction with the Calvin cycle of photosynthesis in plants which  of them produces NADPH?

1. Neither the light reactions nor the Calvin cycle
2. Light reaction alone
3. Occurs in the chloroplast but is not part of photosynthesis
4. The Calvin cycle alone
5. Both the light reactions and the Calvin cycle

Answer 1

Answer is 2-LIGHT REACTIONS ALONE.

EXPLANATION-

In the first step of photosynthesis, ATP and NADPH are produced using the light-dependent reactions,Then ATP and NADPH produced by the light reactions are used by the Calvin cycle to make carbohydrates.
