How is NADPH used for the process of photosynthesis?

In photosynthesis, NADPH is an electron carrier that is used to reduce CO2 into sugars. NADPH is generated during the light reactions of photosynthesis, when light energy is used to split water molecules. The electrons from the water molecules are then used to reduce NADP+ to NADPH.

NADPH is then used in the Calvin cycle to reduce CO2 into sugars. The Calvin cycle is a series of chemical reactions that use the energy from ATP and NADPH to convert CO2 into glucose.

NADPH is an essential component of photosynthesis. Without NADPH, the Calvin cycle could not occur and plants would not be able to produce sugars.
