Problem 10 Tutorial: Overall result of photosynthesis

An overall result of photosynthesis in plants is the use of electrons from water to reduce:

Photosynthesis equation

The overall result of photosynthesis in plants (i.e. light and dark reactions) is summarized in the equation of photosynthesis.

Water is oxidized to oxygen. The electrons from water are first used to reduce NADP+ to NADPH. NADPH is subsequently reoxidized during the reactions of carbohydrate biosynthesis of the Calvin Cycle. The overall fate of the electrons from water is in the reduction of carbon dioxide to glucose.
