Protons light reactions
Light-dependent reactions is jargon for certain photochemical reactions that are involved in photosynthesis, the main process by which plants acquire energy. There are two light dependent reactions, the first occurs at photosystem II (PSII) and the second occurs at photosystem I (PSI), PSII absorbs a photon to produce a so-called high energy electron which transf… Webb8 apr. 2024 · Photoreactions of nitrobenzene derivatives have been studied since the early 1900s, [1] and three types of possible reactions are currently known: intermolecular H abstraction, intramolecular H abstraction, and addition to double bond. [2,3] In a typical intermolecular H abstraction, a nitro radical produced by photoirradiation of a …
