Question

In protoplasm, fat is stored in the form of
A. Polypeptide
B. Triglyceride
C. Polysaccharide
D. Nucleosides

Answer 1

Hint: The cytoplasm and nucleoplasm combines to form the protoplasm. The protoplasm is said to be a living part of the cell. A plasma membrane surrounds it. Protoplasm has different biomolecules: water, amino acids, monosaccharides, proteins, lipids and nucleic acids. Protoplasm has the genetic material of a cell and it controls all the activities.

Complete answer:
> Polypeptide: It has many amino acid residues which form a chain of whole protein molecules. Fat is not the factor here.

> Triglyceride: They are the types of lipids which are also called fats. They come from food sources like oils and butter. Therefore these are a type of form where fats are stored. Hence, it is the most appropriate answer.

> Polysaccharides: Many small monosaccharides combine with each other to form polysaccharides. They are the form of carbohydrates that are found in food. There are three vital polysaccharides that we are well acquainted with. They are the starch, glycogen and cellulose.

> Nucleosides: They have five carbon sugars and they have purines or pyrimidine as base which are linked to sugar.

Hence, the correct answer is option (B).

Note: In the structure of triglycerides, glycerol molecules are bound to three fatty acid chains. There is a well-known phenomenon termed as lipolysis in which the triglycerides are broken down to release fatty acids which further secretes lipases and bile. It is important to understand that triglycerides are difficult to be absorbed as a whole into the cells of the body from the bloodstream and therefore they have to be broken down into small components for better utility.
