Photosynthesis is a process in which energy from sunlight is harvested and used to fix CO2 into carbohydrates. Photosynthesis occurrs in bacteria, algae, phytoplankton and higher plants. During photosynthesis the solar energy is trapped by light-harvesting complexes, and used to split a donor molecule, generating high potential electrons that are channeled to NADP+, forming NADPH, which can be used to reduce CO2.
In oxygenic photosynthesis the donor molecule is water, resulting in the release of molecular oxygen. Some bacteria perform anoxygenic photosynthesis, in which different donor molecules are used for production of high potential electrons. An example are phototrophic sufur bacteria, which use sulfide, releasing molecular sulfur as a by-product.
Photosynthesis is divided into two general subprocesses: the "light reactions" and the "dark reactions". The light reactions comprise the trapping of sunlight, the production of NADPH and ATP, and the release of molecular oxygen (see photosynthesis light reactions).
