Reactants of photosystem 2
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 … Web2) 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.

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. 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 .
WebDec 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 … WebSep 1, 2024 · The light-dependent reactions involve two photosystems called Photosystem I and Photosystem II. These photosystems include units called antenna complexes …
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. WebFeb 2, 2024 · Step 2: Generation of ATP by Electron Transport Chain The electrons released from photosystem II enter a chain of proteins known as electron transport chain (ETC). They move from PSII to a small lipid-soluble molecule, plastoquinone (Pq), and then to a protein complex called cytochrome b6f.
WebPhotosystem II obtains electrons by oxidizing water in a process called photolysis. Molecular oxygen is a byproduct of this process, and it is this reaction that supplies the …
