Electrons first travel through photosystem II and then photosystem I. Molecules called pigments absorb energy from light.The main pigment in photosynthesis is called chlorophyll. Photosystems exist in the membranes of thylakoids. ATP. The principal product of photosynthesis (sugar) is a high-energy molecule, but the reactants (carbon dioxide and water), are low-energy molecules, so the process of photosynthesis needs an energy source to drive it. • Know the overall reaction of photosynthesis including products and reactants, and be able to follow the path of atoms through the process as depicted in Figure 10.5.

Production of ATP 21. •Within the stroma (fluid) of chloroplasts carbon dioxide is built into sugars. •In chloroplasts, the green pigments that absorbs light energy is chlorophyll, located within the thylakoid Photosystem is the form of pigments on the thylakoid membrane1. Photosystem I was discovered first. Later, photosystem II was discovered and found to be earlier in the electron transport chain. This pathway occurs inthe thylakoid membranes and requires participation of two light-gathering units:photosystem I (PS I) and photosystem II (PS II).

During photosynthesis, plants used the sun's energy to change water and carbon dioxide into glucose, a carbohydrate energy source. Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Plant cells take in water, sunlight, and carbon dioxide in order to create energy. 1. •In chloroplasts, the green pigments that absorbs light energy is chlorophyll, located within the thylakoid The light reaction occurs in the thylakoid membrane of the chloroplast and involves two photosystems, photosystems I and II, and the electron transport chain. State the reactants and the products for the light-dependent reactions. A Photosynthesis can revert from a noncyclic to cyclic electron flow, producing. oxygen. Each NADPH is made by exciting two electrons from water in photosystem II and then again in photosystem I. The light reaction occurs in the thylakoid membrane of the chloroplast and involves two photosystems, photosystems I and II, and the electron transport chain. Most of the removed electrons and hydrogen ions ultimately are transferred to carbon dioxide (CO 2), which is reduced to organic products. H2O,NADP,ADP and Pi are the reactants. Ferredoxin then "hands" the electron to NADP which then adds a H+ from the stroma to form NADPH. The reactants of photosynthesis are water, sunlight, and carbon dioxide. How light energy is used to make ATP and NADPH. A photosystem has a similar collection of pigment molecules that focus the energy to a reaction center where the electrons are ejected from the molecule. •Within the stroma (fluid) of chloroplasts carbon dioxide is built into sugars. Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Carbon dioxide 31. Photosystem II uses a form of chlorophyll a known as P680. It accepts electrons produced from sunlight-excited chlorophyll and transfers them to the enzyme ferredoxin: Catalyzes the transfer of electrons from Fd to NADP+, two electrons are required its reduction to NADPH, whic is at a higher energy level and contains electons that are more avaliable for reactions of the calvin cylce, How PSI and PSII are linked via the z-scheme.
