WebPhotosynthesis occurs in two stages: the light-dependent stage, which takes place in the thylakoids, and the light-independent stage, which takes place in the stroma. Light energy is used to breakdown water (photolysis) to produce hydrogen ions, electrons and oxygen in the thylakoid lumen. A proton gradient is formed due to the photolysis of ... Webphosphorylation. the process by which a kinase or other enzyme causes a substrate molecule to gain a phosphate group from ATP or another phosphate donor. This is a transesterification process that produces a phosphorylated substrate and ADP. PO2OH2- replaces an OH- on the substrate. Glycolysis.
