Non-cyclic Electron Transport in Photosynthesis
Photophosphorylation refers to the use of light energy to ultimately provide the energy to convert ADP to ATP, thus replenishing the universal energy currency in living things. In the simplest systems in prokaryotes, photosynthesis is used just for the production of energy, and not for the building of any biological molecules. But in plants the photosynthesis process also provides energy in the form of reduced coenzymes which drive the process of biochemical synthesis culminating in the production of glucose and other sugars. This process uses both Photosystem II and Photosystem I acting in series. The above illustration is patterned after Moore and shows some of the steps of the non-cyclic electron transport process.
