Define photophosphorylation and non - cyclic photophosphorylation.

Photophosphorylation is the process in which the synthesis of ATP from ADP and phosphate that occurs in a plant using radiant energy absorbed during photosynthesis

Non-cyclic photophosphorylation is a two-stage process involving two different chlorophyll photosystems in the thylakoid membrane.

Hence, the correct answer is:

Photophosphorylation is the process of utilizing light energy from photosynthesis to convert ADP to ATP. It is the process of synthesizing energy-rich ATP molecules by transferring the phosphate group into ADP molecules in the presence of light.

The photophosphorylation process which results in the movement of the electrons in a non-cyclic manner for synthesizing ATP molecules using the energy from excited electrons provided by photosystem II is called non-cyclic photophosphorylation
