Question

A major site for the synthesis of lipids is ______.
A. RER
B. SER
C. Symplast
D. Nucleoplasm

Answer 1

Hint: Lipids are any class of organic compounds that are either fatty acids or derivatives which are insoluble in water and are soluble in the organic solvents. These include more steroids and natural waxes. Here, we are going to find the major site for the synthesis of the lipids. Through some of the ideas, it could be found and analyzed.

Complete answer:
Lipids are the compounds that are insoluble in water. These function as the energy-stored molecules and also as the chemical massagers. This is the macro biomolecule which is soluble in the non-polar solvents. Endoplasmic reticulum is the organelle which forms an interconnected network of the flattened sacs which are commonly known as cisternae. This is classified into two types like rough endoplasmic reticulum and smooth endoplasmic reticulum. The cytoplasm’s inner core is known as endoplasm. The smooth endoplasmic reticulum is the major site for the synthesis of the lipids and also it lacks the ribosomes whereas the rough endoplasmic reticulum is decorated with ribosomes and these are the sites of the protein synthesis. These are abundant in both liver and gonad cells. In smooth endoplasmic reticulum the lipids like hormones are synthesized. So, it is clear that smooth endoplasmic reticulum is the major site in the synthesis of lipids.

Hence, the correct answer is Option B.

Note:
   Lipids are used in the energy production in our body. These are used to insulate and protect the body. These are the storage compounds that serve to reserve the energy of the body. This also regulates the permeability of the enzymes. These also act as the electric insulators. Their presence in our body helps in the digestion as well as absorption. They also serve as the soluble vitamins.
