GENERAL HISTOLOGY

Detailed explanation-1: -Smooth E R (SER) is associated with the production and metabolism of fats and steroid hormones.

Detailed explanation-2: -The SER is a storage site for calcium within cells. Calcium is pumped into the SER by active transport and released in response to hormonal signals. This is particularly important in muscle cells where the SER is so prominent it has a special name, the sarcoplasmic reticulum.

Detailed explanation-3: -Smooth ER is responsible for the synthesis of essential lipids such as phospholipids and cholesterol. Smooth ER is also responsible for the production and secretion of steroid hormones. It is also responsible for the metabolism of carbohydrates.

Detailed explanation-4: -Smooth endoplasmic reticulum acts as a lipid production site. SER is abundant in cells involved in the production of lipid and lipid derivatives like the oil glands of the skin, ovaries, and testes.
