Photophosphorylation is a process in which?

Photophosphorylation is a process in which Light energy is converted into chemical energy in the form of ATP.
It is the conversion of ADP to ATP using the energy of sunlight by activation of PSII. This involves the splitting of the water molecule into oxygen and hydrogen protons (H⁺), a process known as photolysis.
Cyclic photophosphorylation occurs in both aerobic and anaerobic conditions, driven by the main primary source of energy available to living organisms, which is sunlight.
