Photosynthesis involves the transfer and harvesting of energy from sunlight and the fixation of carbon dioxide into carbohydrates. This process occurs in higher plants, including Solanum lycopersicum. Oxygenic photosynthesis requires water, which acts as an electron donor molecule. The reactions which involve the trapping of sunlight are known as "light reactions", and result in the production of NADPH, adenosine triphosphate, and molecular oxygen. The "dark reactions" are known as the Calvin cycle, and involve the use of the products of the light reactions to fix carbon dioxide and produce carbohydrates.
