Cyclic light reaction

WebMay 14, 2024 · One likely answer: cyclic photophosphorylation. In cyclic photophosphorylation, the electrons expelled by the energy of light absorbed by photosystem I pass, as normal, to ferredoxin (Fd). But instead of going on to make NADPH, they pass to plastoquinone (PQ) and on back into the cytochrome b 6 /f complex. WebAlternatively, electrons may be transferred only by light reaction I, in which case they are recycled from ferredoxin back to the intermediate carriers. This process is called cyclic electron flow. Evidence of two light reactions Many lines of evidence support the concept of electron flow via two light reactions.

WebOct 22, 2024 · Cyclic Photophosphorylation is the process in which ADP converts into ATP to generate energy for the immediate need of the cells. Only one photosystem (PS I) is used in cyclic photophosphorylation, and there is no decrease of NADP +. When Photosystem I absorbs light, the excited electron may enter an electron transport chain … WebApr 9, 2024 · The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. The light-dependent reactions can be summarized as follows: 12 H 2 O + 12 NADP + + 18 ADP + 18 P i + light and chlorophyll yields 6 O 2 + 12 NADPH + 18 ATP. WebIn a process called non-cyclic photophosphorylation (the “standard” form of the light-dependent reactions), electrons are removed from water and passed through PSII and PSI before ending up in NADPH. This process requires light to be absorbed twice, once in each photosystem, and it makes ATP. conty et al 2010
