WebThey also detoxify many poisons that may enter the body. Many of these oxidation reactions release hydrogen peroxide, H 2 O 2, which would be damaging to cells; however, when these reactions are confined to peroxisomes, enzymes safely break down the H 2 O 2 into oxygen and water. For example, alcohol is detoxified by peroxisomes in liver cells. WebPeroxisomes are organelles that sequester diverse oxidative reactions and play important roles in metabolism, reactive oxygen species detoxification, and signaling. Oxidative … WebPeroxisomes are involved in the oxidation of variety of substances. It is a two step reaction (Fig. 14.5). In first step, oxidase enzymes present in peroxisomes catalyse the oxidation of amino acids, uric acid, lactic acid, and other substances using molecular oxygen as the oxidizing agent and forming H 2 O 2 . shooting star candle
