Detailed explanation-1: -Explanation: Smooth endoplasmic reticulum (ER) is devoted almost exclusively to the manufacture of lipids, and in some cases the metabolism of lipids and their associated products. Smooth ER synthesizes lipids, phospholipids, and steroids. It also carries out the metabolism of carbohydrates and drug detoxification.

Detailed explanation-2: -The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.

Detailed explanation-3: -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-4: -The enzymes that synthesize the lipid components of lipoproteins are located in the membrane of the smooth ER, which also contains enzymes that catalyze a series of reactions to detoxify both lipid-soluble drugs and various harmful compounds produced by metabolism.

Detailed explanation-5: -Cytochrome P450s are a large family of enzymes resident in the membrane of the smooth endoplasmic reticulum. These enzymes of the smooth endoplasmic reticulum help detoxify drugs and poisons, especially in liver cells.
