Answer
Cyclic electron transport provides energy to support carbon fixation. This pathway uses PS I and electron transport to produce ATP. The process is cyclic because an electron is transferred from an excited chlorophyll molecule and recycled back to the same chlorophyll.

Cyclic electron transport provides energy to support carbon fixation. This pathway uses PS I and electron transport to produce ATP. The process is cyclic because an electron is transferred from an excited chlorophyll molecule and recycled back to the same chlorophyll. ATP is generated as proton concentration increases in the lumen. This pushes protons through the membrane, where ATP synthase takes advantage of the gradient to synthesize ATP.
