KVPYKVPY 2019

Solution:

Product of cyclic photophosphorylation is ATP. In cyclic photophosphorylation only one photosystem (PS-I) is involved when light is absorbed by PS-I excited electrons enters into electron transport chain to produce ATP.
Both ATP and NADPH are produced in non-cyclic photophosphorylation, which includes both photosystems (PS-I and PS-II)
