Answer Details
The process whereby electrons are emitted from chlorophyll and returned to it unchanged is known as cyclic photophosphorylation. During this process, light energy is absorbed by chlorophyll and used to excite electrons, which then move along an electron transport chain and ultimately return to the chlorophyll molecule. This results in the generation of ATP (adenosine triphosphate), which is an important energy source for the cell. Unlike non-cyclic photophosphorylation, which involves the transfer of electrons to an electron acceptor and the subsequent generation of NADPH in addition to ATP, cyclic photophosphorylation only generates ATP.
