FAQs on Biomolecules Mock Test for JEE Main 2025-26: Practice, Analyze, Succeed
1. What are biomolecules?
Biomolecules are organic molecules that are essential for the structure and function of living organisms. They include carbohydrates, proteins, lipids, and nucleic acids, each performing unique biological roles in metabolic processes, cell structure, and genetic information storage.
2. What are the different types of biomolecules?
Biomolecules are mainly classified into four major types: carbohydrates (sugars and starches), proteins (polymers of amino acids), lipids (fats and oils), and nucleic acids (DNA and RNA). Each type has specific structural and functional properties essential for life.
3. What are monosaccharides? Give an example.
Monosaccharides are the simplest carbohydrates with a single sugar unit. They are basic building blocks of higher carbohydrates. An example of a monosaccharide is glucose (C₆H₁₂O₆).
4. Describe the structure of an amino acid.
An amino acid has a central α-carbon bonded to an amino group (–NH₂), a carboxyl group (–COOH), a hydrogen atom, and a variable side chain (R group). The R group distinguishes each amino acid.
5. What is the difference between DNA and RNA?
DNA (Deoxyribonucleic acid) contains deoxyribose sugar and stores genetic information, while RNA (Ribonucleic acid) has ribose sugar and is involved in protein synthesis. DNA is double-stranded, while RNA is generally single-stranded.
6. Define enzymes and their significance in biological reactions.
Enzymes are biological catalysts made of proteins. They speed up biochemical reactions by lowering the activation energy, ensuring vital processes like digestion and metabolism occur efficiently in living organisms.
7. What are the functions of carbohydrates in living organisms?
Carbohydrates function as the main energy source, provide structural support (cellulose in plants, chitin in arthropods), and serve as components of cell membranes and cell recognition processes.
8. What is a peptide bond?
A peptide bond is a covalent bond formed between the amino group of one amino acid and the carboxyl group of another, resulting in the release of a water molecule. This bond links amino acids to form proteins.
9. Differentiate between saturated and unsaturated fatty acids.
Saturated fatty acids contain only single bonds between carbon atoms, making them solid at room temperature (e.g., butter). Unsaturated fatty acids contain one or more double bonds, making them liquid at room temperature (e.g., oils).
10. Explain the lock and key model of enzyme action.
The lock and key model suggests that an enzyme's active site is specifically shaped to fit the substrate, just as a key fits into a lock, enabling the enzyme to catalyze only specific reactions.
11. What is the role of nucleic acids in living organisms?
Nucleic acids such as DNA and RNA store, transmit, and express genetic information. DNA holds the genetic blueprint; RNA helps in protein synthesis and gene expression.
12. Name two tests used to detect carbohydrates and explain one of them.
Two common tests are the Benedict's Test and Molisch's Test. The Benedict's Test involves adding Benedict's reagent to a carbohydrate solution and heating; reducing sugars turn the solution from blue to orange-red, indicating their presence.
