![]() It refers to the light reaction of the photosynthetic process, which predominately occurs in green plants and algae. Definition of Noncyclic Photophosphorylation It does not require water hydrolysis to replenish electron loss. The organisms undergoing cyclic photosynthesis restore electron supply, due to which reduction of NADP does not occur. Thus, the electrons move to and fro within the photosystem by following a cyclic path. It is termed cyclic because electrons return to the photosystem I after releasing the chemical energy, i.e. Cyclic photophosphorylation only involves photosystem I (P700). It refers to the light reaction of the photosynthetic process, which prevalently occurs in the prokaryotes or photosynthetic bacteria. Occurs when the CO2 concentration is less in the atmosphereĭefinition of Cyclic Photophosphorylation Molecular oxygen is generated in noncyclic photophosphorylationĪTP and NADPH are produced in this process Oxygen is not generated during cyclic photophosphorylation Reaction centre PS-II first excites the electron Reaction centre PS-I first excites the electron ![]() It involves photosystem-I and photosystem-II The electrons flow linearly in a zig-zag pattern ![]() The electrons flow in a cyclic or circular pattern ![]() Primarily occurs in higher plants, algae and cyanobacteria Predominantly occurs in photosynthetic bacteria Noncyclic photophosphorylation refers to the process which produces ATP from noncyclic electron transport chain in light reactions of photosynthesis Content: Cyclic Vs Noncyclic PhotophosphorylationĬyclic photophosphorylation refers to the process which produces ATP during the cyclic electron transport chain of light dependent photosynthesis ![]()
