Question

Select the correct matching in the following pairs.
A. Rough ER - Synthesis of glycogen
B. Rough ER - Oxidation of fatty acids
C. Smooth ER - Oxidation of phospholipids
D. Smooth ER - Synthesis of lipids

Answer 1

The smooth endoplasmic reticulum, or SER, is an organelle that is found in both animal cells and plant cells. An organelle is a subunit within a cell that has its specialized function. The main function of the smooth Endoplasmic reticulum(SER) is to make cellular products such as hormones and lipids.

Complete answer: The smooth endoplasmic reticulum(SER) packages proteins for transportation, synthesizes membrane phospholipids, and release of calcium. Other functions of the smooth endoplasmic reticulum include the transformation of bile pigments, glycogenolysis (the process of breakdown of glycogen), and detoxification of many drugs and chemical agents. The smooth endoplasmic reticulum(SER) is another organelle in eukaryotic cells that synthesizes lipids. This organelle is located near the rough endoplasmic reticulum(RER), and it produces phospholipids and cholesterol that help to stabilize the membranes of the entire cell. The ribosomes in the rough endoplasmic reticulum(RER) manufacture proteins. These proteins are manufactured from the chains of amino acids.
Smooth endoplasmic reticulum (SER) is a system of smooth membranes (membranes not having ribosomes) within the cytoplasm of plant and animal cells. It forms a connection between the cell and nuclear membranes. It is the site of important metabolic reactions, it also includes phospholipid and fatty acid synthesis. In animal cells, lipid-like steroidal hormones are also synthesized by the smooth endoplasmic reticulum.
So, the correct option is D

Note: Smooth ER (SER) acts as a storage organelle. It is important in the formation and storage of lipids and steroids. Steroids are a type of ring-like organic molecule used for many purposes in an organism. They are not always about building the muscle mass of a weightlifter.
