Cyclic reaction of photosynthesis

WebApr 9, 2024 · The overall reaction for photosynthesis is as follows: 6 CO 2 + 12 H 2 O in the presence of light and chlorophyll yields C 6 H 12 O 6 + 6 O 2 + 6 H 2 O. Oxygenic photosynthesis is composed of two stages: the light-dependent reactions and the light-independent reactions. WebThe first end-product of photosynthesis was this 3-carbon chain, this glyceraldehyde 3-phosphate. But then you can use that to build up glucose or any other carbohydrate. ... Well, if we're talking about non-cyclic oxidative photophosphorylation, or non-cyclic light reactions, the final electron acceptor. So after that electron keeps entering ...

What Happens in the Light Reaction of Photosynthesis?

Web2. Photosystem II (PS II) donates electrons to photosystem I where NADP+ is reduced. 3. This system is responsible for the photolysis of water and involves the evolution of molecular oxygen. 4. PS II is located on the inner surface of the thylakoid, i.e., in the stroma and non-appressed regions of grana. 5. The reaction centre of PS II is P 680. WebExperimentally, cyclic phosphorylation can therefore be distinguished from any other kind of chloroplast photophosphorylation by two criteria: 1) the resistence to CMU, DCMU and orthophenanthroline; 2) the fact that light absorbed by photosystem I at the far-red end of chlorophyll a absorption spectrum is sufficient to activate the reaction.

WebCyclic Electron Flow. The light dependent reactions begin with a structure called Photosystem I. Photosystem I is an integral membrane protein complex on the thylakoid membrane that absorbs sunlight with a photosynthetic pigment. The optimal wavelength that this pigment absorbs is P700.

WebIt has been confirmed by many studies that the cyclic flow of electrons around PSI is important for the photosynthesis of higher plants [22,33]. The cyclic electron flow around PSI is stimulated by many adverse environmental conditions, including drought and salt stress [19,49,50].

WebVideo transcript. - [Voiceover] We've seen in previous videos that photosynthesis can be broken down into the light-dependent reactions and the Calvin cycle. And the light-dependent reactions is where we take light as an input along with water, and we'll see the water is actually a source of electrons, and we can use that to store energy in the ...

WebFigure 8.19 The light-dependent reactions of photosynthesis (left) convert light energy into chemical energy, forming ATP and NADPH. These products are used by the light-independent reactions to fix CO 2, ... Only PSI is used during cyclic photophosphorylation; the high-energy electron of the PSI reaction center is passed to an ETS carrier and ... WebThe light-dependent reactions of photosynthesis convert solar energy into chemical energy, producing ATP and NADPH or NADH to temporarily store this energy. In oxygenic photosynthesis, H 2 O serves as the electron donor to replace the reaction center electron, and oxygen is formed as a byproduct.
