Reactants of photosystem 2
WebApr 12, 2024 · Photosystem II or PS II is the membrane-embedded-protein-complex, consisting of more than 20 subunits and around 100 cofactors. The light is absorbed by the pigments such as carotenoids, chlorophyll, … 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.

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. 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.
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? WebThe series of light-dependent reactions begins when sunlight hits a molecule of chlorophyll, located in photosystem II. This excites an electron, which leaves the chlorophyll molecule and travels along the thylakoid membrane via a series of carrier proteins (known as the electron transport chain).
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. WebMay 25, 2024 · While at photosystem II and I, the electrons gather energy from sunlight. How do they do that? Chlorophyll, which is present in the photosystems, soaks up light energy. …

WebThe 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. im testing somethingWebDec 24, 2024 · In photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In photosystem I, the electron comes from the … litho- meaningWeb2) In many situations phosphate is a limiting nutrient, so needing to make more ATP could severely limit the plants ability to store energy. 3) Fixed carbon (e.g. glucose) can be converted into other molecules the plant needs including: • cellulose for structure • lipids for long term energy storage, cell membranes, etc. lithomaxWeb2.
