Detailed explanation-1: -The smooth endoplasmic reticulum (Fig. 1.5A) is associated with carbohydrate metabolism and many other metabolic processes, including detoxification and synthesis of lipids, cholesterol and steroids.
Detailed explanation-2: -Explanation: Smooth endoplasmic reticulum (ER) synthesizes lipids and detoxifies harmful substances.
Detailed explanation-3: -SMOOTH ENDOPLASMIC RETICULUM Smooth ER is devoted almost exclusively to the manufacture of lipids and in some cases to the metabolism of them and associated products. In liver cells for example smooth ER enables glycogen that is stored as granules on the external surface of smooth ER to be broken down to glucose.
Detailed explanation-4: -To perform the function of detoxification, Smooth Endoplasmic Reticulum (SER) doubles its surface area. Once the specific drug or toxin has been eliminated from the body, the excess SER is destroyed by a process called autophagocytosis.
Detailed explanation-5: -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.
