Detailed explanation-1: -The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.

Detailed explanation-2: -The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors. In addition, it is involved in carbohydrate metabolism.

Detailed explanation-3: -The proteins made by the rough endoplasmic reticulum are for use outside of the cell. Functions of the smooth endoplasmic reticulum include synthesis of carbohydrates, lipids, and steroid hormones; detoxification of medications and poisons; and storage of calcium ions.

Detailed explanation-4: -Structural lipids are mostly synthesized in the endoplasmic reticulum (ER), from which they are actively transported to the membranes of other organelles.

Detailed explanation-5: -Lipid synthesis takes place in the smooth endoplasmic reticulum and protein is synthesized by the ribosomes of rough endoplasmic reticulum. They are the types of the endoplasmic reticulum.
