Reactants of photosystem 2
Web2. The reactants of photosynthesis are carbon dioxide and water. We’ve established that plants need carbon dioxide (CO2) and water (H2O) to produce their food, but where do these reactants come from and how do they get where they need to go inside the plant? WebPhotosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin .

WebWhat best describes the roles of photosystem I and photosystem II in the process of photosynthesis? answer choices They absorb sunlight and transfer the energy to electrons. They form ATP as hydrogen ions cross the thylakoid membrane. They absorb sunlight and distribute the energy as heat. 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 are then transferred through a variety of coenzymes and cofactors to reduce plastoquinone to …

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 … WebDec 24, 2024 · photosystem: Either of two biochemical systems active in chloroplasts that are part of photosynthesis. Photosynthesis takes place in two sequential stages: The light-dependent reactions; The light-independent reactions, or Calvin Cycle. Light-Dependent Reactions Just as the name implies, light-dependent reactions require sunlight.
WebKey reactions include the conversion of glucose to glucose-6-phosphate by hexokinase, the production of ATP by phosphoglycerate kinase, and the production of NADH by glyceraldehyde-3-phosphate dehydrogenase. Describe the major steps in the link reaction and Krebs cycle, including reactants, products and key reactions.
WebThe photosystem II complex replaced its lost electrons from H 2 O, so electrons are not returned to photosystem II as they would in the analogous cyclic pathway. Instead, they are transferred to the photosystem I complex, which boosts their energy to a higher level using a second solar photon. solway foodsWebThe light reactions begin when a photon hits a chlorophyll molecule in photosystem II, exciting its electrons. At the same time, a water is split by enzymes in the thylakoid membrane into 2 H⁺ ions, one oxygen atom, and a pair of electrons. The hydrogen ions are released inside the membrane. solway fitness dumfriesWebThe series of light-dependent reactions begins when sunlight hits a molecule of chlorophyll, located in photosystem II.
