what is a photolysis?
Answers
Answer:
Photodissociation, photolysis, or photodecomposition is a chemical reaction in which a chemical compound is broken down by photons. It is defined as the interaction of one or more photons with one target molecule. Photodissociation is not limited to visible light.This part of photosynthesis occurs in the granum of a chloroplast where light is absorbed by chlorophyll; a type of photosynthetic pigment that converts the light to chemical energy. This reacts with water (H2O) and splits the oxygen and hydrogen molecules apart.Thus, the net oxidation reaction of water photolysis can be written as: 2 H2O + 2 NADP+ + 8 photons (light) → 2 NADPH + 2 H+ + O. The free energy change (ΔG) for this reaction is 102 kilocalories per mole.
Answer:
Photolysis is defined as the decomposition of substances on exposure to light, while photo-oxidation is the oxidation of a substance on exposure to light. Irradiation of tryptophan with UV light results in the formation of a tryptophan radical and a hydrated electron.
