Chlorophyll a and b absorb light in the thylakoid mostly blue, red, and orange. 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 form of ATP and NADPH and as a by-product we produce molecular oxygen which is very in the last video we learned a little bit about both photosynthesis it and we know in very general terms it's the process where we start off with photons and water and carbon dioxide and we use that energy and the photons to fix the carbon and now there's this idea of carbon fixation is essentially taking carbon in a gaseous form in this case carbon dioxide and fixing it into a solid structure See Figure 1 for a schematic of this process.

How do the reactant molecules of photosynthesis reach the chloroplasts in leaves?

The primary function of the photosystem I in NADPH synthesis, where it receives the electrons from PS II, and the photosystem II is in the hydrolysis of water and ATP synthesis. Core Composition in the PSI is made up of two subunits which are psaA and psaB, and PS II is made up of two subunits made up of D1 and D2.

Its name is derived from the Greek words χλωρός, khloros and φύλλον, phyllon. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. Conversely, it is a poor absorber of green and Under certain conditions, the photoexcited electrons take an alternative path called cyclic electron flow, which uses photosystem I (P700) but not photosystem II (P680). This process produces no NADPH and no O 2, but it does make ATP. This is called cyclic photophosphorylation.

energy is transferred to a reaction center where electrons are actually moved into electron transport chains Each photosystem II contains at least 99 cofactors: 35 chlorophyll a, 12 beta-carotene, two pheophytin, two plastoquinone, two heme, one bicarbonate, 20 lipids, the Mn 4 CaO 5 cluster (including two chloride ions), one non heme Fe 2+ and two putative Ca 2+ ions per monomer.

Three major protein complexes are involved in running the "Z" scheme: (1) Photosystem II; (2) Cytochrome bf complex (containing Cytb 6; FeS; and Cytf ) and (3) Photosystem I. The diagram does not show where and how ATP is made. For a description of how the Z Scheme operates, click here.

It requires ribulose—1, -biphosphate or RuBP as acceptor of carbon dioxide and RuBP carboxylase or rubisco as enzyme.
