WebIn cyclic electron flow (CEF), electrons are recycled around photosystem I. As a result, a transthylakoid proton gradient (ΔpH) is generated, leading to the production of ATP without concomitant production of NADPH, thus increasing the … WebMar 1, 2011 · Two major pathways of cyclic flow have been identified, involving either a complex termed NDH or mediated via a pathway involving a protein PGR5 and two …

WebJun 21, 2024 · The NDH pathway mediates electron flow from ferredoxin to the plastoquinone pool via the NAD (P)H dehydrogenase-like (NDH) complex in the thylakoid membranes (Peltier et al. 2016 ). Because the NDH complex is a homologue of complex I in the respiratory chain, it functions as a proton pump across the thylakoid membrane. WebMar 9, 2024 · The pathway is referred to as ‘linear electron flow’ (LEF) because the electrons originate from water splitting at photosystem II (PSII) and are transferred in a linear progression to PSI via plastoquinone/plastoquinol (PQ/PQH 2) and the cytochrome b 6f complex (Cyt b 6f ), pumping protons across the thylakoid membrane ( Hill and Bendall, … jobs in schenectady ny for 16 year olds

WebJan 3, 2024 · The electrons are then passed through an electron transport chain, generating ATP via a proton motive force. Electrons are then passed to photosystem I ( PSI ), where they get hit by another photon of light, decreasing their reduction potential even more. Webelectron pathway. The general features of a widely accepted mechanism for photoelectron transfer, in which two light reactions (light reaction I and light reaction II) occur during the … WebThe electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center. When light energy is absorbed by pigments and passed inward to the reaction center, the electron in P700 is boosted to a very high energy level and transferred … Besides introducing fixed carbon and energy into ecosystems, photosynthesis … Cellular respiration is the process by which cells derive energy from glucose.
