What best represents the relationships between the light reactions and the Calvin cycle?

Difference:

The Calvin cycle converts carbon dioxide to carbohydrate.

CO2 --------> (CH2O)

This process requires an energy source and a hydrogen source, as well as carbon dioxide.

The energy source is ATP. The hydrogen source is NADPH.

Both of these substances are produced by the light-dependent reactions.

RELATIONSHIP:

The light reactions and the Calvin cycle are both stages of photosynthesis. The light reactions (photosystems) produce NADPH, ATP, and Oxygen gas. The oxygen is released as a waste product but the NADPH and ATP enter the Calvin cycle, which produces a simple sugar molecule
