AP BIOLOGY

Detailed explanation-1: -Smooth ER. The smooth endoplasmic reticulum (SER) is continuous with the RER but has few or no ribosomes on its cytoplasmic surface. Functions of the SER include synthesis of carbohydrates, lipids, and steroid hormones; detoxification of medications and poisons; and storage of calcium ions.

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: -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.

Detailed explanation-4: -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-5: -What organelle is responsible for this detoxification? Explanation: Smooth endoplasmic reticulum is primarily responsible for the production of lipids and for the detoxification of drugs and toxins from the body.
