In the presence of light, the light reaction, also known as photolysis, takes place.
The grana of chloroplasts are where it usually happens.
In the photosystem, pigment molecules are present, chlorophyll is a pigment found in plants that plays an active role in light reactions such as photosynthesis.
The light reaction of photosynthesis yields three products: and.
These molecules are formed during cyclic and non-cyclic photophosphorylation reactions.
