The Light Reactions of Photosynthesis Supply the Calvin Cycle With

Question

The light reactions of photosynthesis supply the Calvin cycle with
A) light energy.
B) CO₂ and ATP.
C) H₂O and NADPH.
D) ATP and NADPH.
E) sugar and O₂.

Accepted Answer

The light reactions of photosynthesis generate ATP and NADPH, which are then used by the Calvin cycle to produce sugar. The other options are incorrect as H₂O and NADPH are produced during the light-dependent reactions and are not supplied to the Calvin cycle, while CO₂ and light energy are utilized by the Calvin cycle, not supplied by it.
