Do plants undergo photosynthesis without PSII or by passing PSII?

Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants, algae, and cyanobacteria. Within the photosystem, enzymes capture photons of light to energize electrons that … Zobacz więcej The oxygen-evolving complex is the site of water oxidation. It is a metallo-oxo cluster comprising four manganese ions (in oxidation states ranging from +3 to +4) and one divalent calcium ion. When it oxidizes water, … Zobacz więcej Inhibitors of PSII are used as herbicides. There are two main chemical families, the triazines derived from cyanuric chloride of which atrazine and simazine are the most commonly … Zobacz więcej Photosynthetic water splitting (or oxygen evolution) is one of the most important reactions on the planet, since it is the source of nearly all the atmosphere's oxygen. Moreover, artificial photosynthetic water-splitting may contribute to the effective use of … Zobacz więcej • Oxygen evolution • P680 • Photosynthesis • Photosystem • Photosystem I • Photosystem II light-harvesting protein Zobacz więcej Witryna1 mar 2024 · Photocatalytic and photoelectrochemical CO 2 reduction of artificial photosynthesis is a promising chemical process to solve resource, energy, and environmental problems.

Witryna7 mar 2024 · Figure 6.4. 5: (a) PSI and PSII are found on the thylakoid membrane. The high-energy electron from PSII is passed to an ETS, which generates a proton motive force for ATP synthesis by chemiosmosis, and ultimately replaces the electron lost by the PSI reaction center. The PSI reaction center electron is used to make NADPH. WitrynaThe main function of PSII is to efficiently split water into oxygen molecules and protons. PSII will provide a steady stream of electrons to PSI, which will boost these in energy and transfer them to NADP + and H + to make NADPH. The hydrogen from this NADPH can then be used in a number of different processes within the plant. [2]
