Chloroplast light reaction

WebMay 25, 2024 · The light-dependent reactions take place in the thylakoid membrane, inside chloroplasts. Since they are light 'dependent' reactions, you can guess that these reactions need light to work. … 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.
