Biology

If the solution lacks ADP and NADP+, both the light-dependent reactions and the Calvin cycle will stop.

The light-dependent reactions rely on ADP and NADP⁺ to produce ATP and NADPH. Specifically, ADP is phosphorylated to ATP and NADP⁺ is reduced to NADPH during these reactions, using energy from light. Without these molecules, the production of ATP and NADPH will not occur, halting the light...
