FAQs on Biomolecules Mock Test 1-2 for JEE Main 2025-26 Preparation
1. What are biomolecules?
Biomolecules are organic compounds produced by living organisms and are essential for various biological processes. They include key classes such as carbohydrates, proteins, lipids, and nucleic acids.
2. What are the four major types of biomolecules?
The four major types of biomolecules are carbohydrates, proteins, lipids, and nucleic acids. Each class serves unique functions, such as energy storage, structural support, catalysis of biochemical reactions, and storage of genetic information.
3. What is the basic unit of carbohydrates?
The basic unit of carbohydrates is the monosaccharide, which is a simple sugar like glucose or fructose. These units can combine to form complex carbohydrates like disaccharides and polysaccharides.
4. How do proteins differ from carbohydrates and lipids?
Proteins are polymers made up of amino acids linked by peptide bonds, whereas carbohydrates are composed of monosaccharides and lipids are formed of fatty acids and glycerol. Proteins primarily function in structure, transport, and enzymatic catalysis, while carbohydrates supply energy, and lipids store energy and provide insulation.
5. What are nucleic acids and their main types?
Nucleic acids are complex biomolecules responsible for storing and transmitting genetic information. The two main types are DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid).
6. Can you differentiate between DNA and RNA?
Both DNA and RNA are nucleic acids, but DNA contains deoxyribose sugar and has thymine as a base, whereas RNA has ribose sugar and uracil instead of thymine. DNA stores genetic information, while RNA plays a crucial role in protein synthesis.
7. What is an enzyme? Explain its role as a biomolecule.
An enzyme is a biological catalyst that speeds up biochemical reactions without being consumed in the process. Enzymes are typically proteins, and they play vital roles in processes such as digestion, metabolism, and cellular regulation.
8. What are the components of a nucleotide?
A nucleotide consists of three components: a nitrogenous base (purine or pyrimidine), a pentose sugar (ribose or deoxyribose), and a phosphate group. Nucleotides are the building blocks of nucleic acids.
9. What is the difference between saturated and unsaturated fatty acids?
Saturated fatty acids contain only single bonds between carbon atoms, making them solid at room temperature, while unsaturated fatty acids have one or more double bonds, resulting in oils that are liquid at room temperature. This structural difference affects their function and role in health.
10. What are polysaccharides? Name two examples.
Polysaccharides are large, complex carbohydrates formed by the linkage of multiple monosaccharide units. Examples include starch and glycogen, which serve as energy storage molecules in plants and animals, respectively.
11. Why are biomolecules important for life?
Biomolecules are essential for life because they participate in processes such as energy production, cell structure formation, enzyme catalysis, genetic information storage and transfer, and regulation of physiological activities. Without these compounds, cells cannot function properly.
12. What is a primary metabolite? Give an example.
A primary metabolite is a biomolecule directly involved in the normal growth, development, and reproduction of an organism. Examples include amino acids, glucose, and nucleotides.
