What Is the Final Electron Acceptor of Photosynthesis?

NADP+, or nicotinamide adenine dinucleotide phosphate, is the final electron acceptor in photosynthesis. NADP+ allows carbon dioxide to assimilate within the Calvin cycle by means of its reducing power. This enables carbon dioxide to be converted into glucose.

Photosynthesis is the biological process that converts light energy into chemical energy. Plants, algae and cyanobacteria are organisms that use photosynthesis. Since photosynthesis releases oxygen as a byproduct, plants and other photosynthetic organisms are responsible for maintaining atmospheric oxygen levels. In addition to the energy it provides, photosynthesis also produces almost all of the organic compounds necessary for life. The efficiency of photosynthesis used by plants is approximately between 3 and 6 percent, with most of the remaining energy dissipated as heat.
