Detailed explanation-1: -Non-cyclic photophosphorylation involves both photosystems I and II. The electron follows a non-cyclic pathway in it. The representation of it is also called Z scheme.
Detailed explanation-2: -The net result of non-cyclic phosphorylation is the formation of NADPH, oxygen and ATP molecules. Oxygen is produced as a waste product of photosynthesis.
Detailed explanation-3: -The other pathway, non-cyclic photophosphorylation, is a two-stage process involving two different chlorophyll photosystems in the thylakoid membrane.
Detailed explanation-4: -Cyclic photophosphorylation involves the use of photosystem-I. When light is absorbed by this photosystem, the excited electron enters the electron transport chain to produce ATP.
