Question

plzz tell me about cyclic and non cyclic photo-phosphorylation.

Answer 1

cyclic p ====>This form of photophosphorylation occurs on the thylakoid membrane. In cyclic photophosphorylation, the high energy electron released from P700 to ps1 flow down in a cyclic pathway.
non cyclic p===>non-cyclic photophosphorylation, is a two-stage process involving two different chlorophyll photosystems. Being a light reaction, non-cyclic photophosphorylation occurs in the frets or stroma lamellae .
