Question

What do theese photosytems do​

Answer 1

Explanation:

Photosystems are the practical components for photosynthesis, well-defined by a specific stain association and connotation patterns, whose work is the absorption and allocation of light energy, which suggests transfer of electrons. Physically, photosystems are initiate in the thylakoid membranes. A photosystem consists of a light-harvesting complex and a reaction center. Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. Photosystem I or PS I and Photosystem II or PS II are the protein-mediated complex, and the main aim is to produce energy (ATP and $NADPH_2$), which is used in Calvin cycle, the PSI uses light energy to convert NADP+ to $NADPH_2$.
