WebSep 11, 2015 · Because light reactions limit photosynthesis at low light intensity, NDH-dependent PS I cyclic electron transport may play a role in energizing photosynthesis in low light. In this... WebCyclic Electron Flow The shift from non-cyclic to cyclic photophosphorylation occurs when the demand for ATP from the Calvin cycle is too high, and the plant responds by initiating cyclic photophosphorylation. Without sufficient ATP, the Calvin cycle will slow, or even stop. The Xanthophyll Cycle Summary of the ‘Light Reactions’
WebJan 1, 2016 · Cyclic photo-phosphorylation in photosynthesis light dependent reaction leads to the formation of ATP and NADPH, and the electrons go from water to PSII to PSI and … WebApr 9, 2024 · The process of cyclic photophosphorylation generally occurs in the thylakoid membrane and makes use of Photosystem I and Chlorophyll P700. During this process of cyclic photophosphorylation, the electrons get transferred back to P700 from the electron acceptor and they do not move to the NADP.
