NEET BIOLOGY

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 rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.

Detailed explanation-3: -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. Meanwhile, the hydrophilic parts of the fats face into the cisternal space.

Detailed explanation-4: -Its composition has two components: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER). The SER is generally used for the creation/ storage of lipids and steroids, while the RER plays a significant role in the synthesis of various proteins.

Detailed explanation-5: -The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes.
