why is photolysis an uncecessary reaction in cyclic photophosphorylation?
Homework Answers
Cyclic photophosphorylation use only one photosystem PSI and not involve reduction of NADP+. It directly excite electron and it enter into ETC and produce ATP. So in this process NADP+ is not reduced so water is no needed to replenish the electron supply.

Construct a concept map with the central theme
"Photophosphorylation". Use lines with arrows to connect and show
the relationship between connected items. Write a word or
short phrase by each arrow to specify the relationship.
Many arrows can originate or terminate from each concept (if
necessary). Arrows should only go one way, and each arrow
should have a linking phrase attached to it.
