Question

Enzymes, vitamins and hormones can be classified into a single category of biological chemicals, because all of these

• A. Are exclusively synthesized in the body of a living organism as at present.
• B. Enhance oxidative metabolism.
• C. Are conjugated proteins.
• D. Help in regulating metabolism.

Answer 1

The correct option is D Help in regulating metabolism.

There are more than thousand of biomolecules involve in living organisms in various biological processes. Some are vitamins, hormones, enzymes, ATP, carbohydrates, lipids, nucleic acids and proteins. Out of these main carbohydrates, proteins, lipids and nucleic acid are main biomolecules which play a vital role in living systems and mainly responsible for almost all biochemical processes. The biological molecules or biomolecules are involved in metabolic activities of living bodies such as plants and animals. Most of the biomolecules in the living cell have some broad functions like:

1. They are essential to cellular and body structure.

2. They act as energy-rich fuels during cellular respiration.

3. The molecules are used to carry information of controlling growth and biological characteristics from one generation to another.

4. They are good catalytic agents for the various chemical processes occur in cell and living body.
