Detailed explanation-1: -The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.

Detailed explanation-2: -The endoplasmic reticulum (ER) is the main site for lipid synthesis.

Detailed explanation-3: -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-4: -Despite the wide distribution of most phospholipid classes throughout organelle membranes, the site of synthesis of each phospholipid class is usually restricted to one organelle, commonly the endoplasmic reticulum (ER).

Detailed explanation-5: -Smooth E R (SER) is associated with the production and metabolism of fats and steroid hormones.
