Key Difference – Cyclic vs Noncyclic Photophosphorylation Photophosphorylation or photosynthetic phosphorylation is a process in which ATP is produced during the light-dependent reactions of photosynthesis. A phosphate group is added to ADP to form ATP, utilizing the proton motive force generated during the cyclic and noncyclic electron transport chains of photosynthesis. The energy is […]
