WebFigure 1 illustrates both linear and cyclic electron flow in the thylakoid membrane. In linear electron flow, energy derived from photons absorbed by pigments in the antenna complexes is used... WebThe electron transfers from pheophytin to plastoquinone (PQ), which takes 2e- (in two steps) from pheophytin, and two H+ Ions from the stroma to form PQH2. This plastoquinol is later oxidized back...
Why is cyclic electron flow necessary? – Wise-Answer
WebApr 10, 2024 · The electrons transfer from pheophytin to plastoquinone, which takes the 2 electrons from Pheophytin, and two hydrogen Ions from the stroma and forms PQH2, which later is broken into PQ, the 2 electrons are released to Cytochrome b6f complex and the two hydrogen ions are left out into thylakoid lumen. WebAll organisms produce a phosphate compound, ATP, which is the universal energy currency of life. In photophosphorylation, light energy is used to pump protons across a biological membrane, mediated by flow of electrons through an electron transport chain. This stores energy in a proton gradient. As the protons flow back through an enzyme called ... curls defining cream

WebCyclic electron flow Both these electron paths are discussed below. Non-cyclic Electron Flow This type of electron flow involves both photosystems I (P700) and photosystem II (P680). The ultimate yield of this type of flow is the synthesis of ATP as well as NADPH. WebDrag the labels onto the diagram to identify how energy flows through an ecosystem. Light --> Glucose --> ATP --> Heat Drag the labels onto the diagram to identify the inputs and outputs of the two stages of photosynthesis. Use only pink labels for pink targets.
