NEET BIOLOGY

Detailed explanation-1: -Smooth endoplasmic reticulum in liver cells of vertebrates helps in detoxifying poisons and drugs. It contains enzymes that catalyze a number of reactions that can make lipid-soluble drugs and metabolic wastes into water-soluble so that these can easily be expelled out from the body.

Detailed explanation-2: -Some types of peroxisomes, such as those in liver cells, detoxify alcohol and other harmful compounds by transferring hydrogen from the poisons to molecules of oxygen (a process termed oxidation).

Detailed explanation-3: -Explanation: Smooth endoplasmic reticulum(ER) is responsible for the detoxification of a number of organic chemicals. The smooth ER converts organic substances into water and other soluble products to allow for excretion.

Detailed explanation-4: -Peroxisomes are organelles that sequester diverse oxidative reactions and play important roles in metabolism, reactive oxygen species detoxification, and signaling. Oxidative pathways housed in peroxisomes include fatty acid -oxidation, which contributes to embryogenesis, seedling growth, and stomatal opening.
