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 endoplasmic reticulum is primarily composed of three-dimensional polygonal networks of tubules called cisternae. They are about 50 nm in diameter in mammals and 30 nm in diameter in yeast.
Detailed explanation-3: -The ER membrane synthesizes nearly all of the major classes of lipids, including both phospholipids and cholesterol, required for the production of new cell membranes.
Detailed explanation-4: -Lipids are made by enzymes embedded in the membrane of the SER. That’s because they have hydrophobic parts that don’t like the watery inside of the organelle.
