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 15, 2024 · Light / Dark Reaction of Photosynthesis DIRECTIONS: Use your textbook, or internet sources to find pictures of the light and dark reactions of photosynthesis. Study the pictures carefully. Draw a detailed diagram that shows both the light and dark reactions of photosynthesis. 1. Diagram must be on 8.5 X 11 inch white paper. 2. 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. WebMay 25, 2024 · While at photosystem II and I, the electrons gather energy from sunlight. How do they do that?
