What to expect: This mock test covers key concepts from the Biomolecules chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Assertion (A): When a living tissue is ground in trichloroacetic acid and strained, two fractions are obtained. Reason (R): The filtrate is called the acid-soluble pool and the retentate is called the acid-insoluble fraction.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
2.Assertion (A): Lipids are placed in the acid-insoluble macromolecular fraction even though their molecular weights do not exceed about 800 Da. Reason (R): On grinding a tissue, membranes break into vesicles that are not water soluble and separate along with the acid-insoluble pool.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
3.To analyse the chemical composition of a living tissue, the tissue is ground in:
- A.Trichloroacetic acid
- B.Concentrated sulphuric acid
- C.Distilled water only
- D.Absolute alcohol
-
4.Almost all enzymes are proteins, but some nucleic acids that behave like enzymes are called:
- A.Ribozymes
- B.Apoenzymes
- C.Coenzymes
- D.Isozymes
-
5.The catalytic cycle of an enzyme is summarised as E + S to ES to EP to E + P. Which statement about this cycle is correct?
- A.Formation of the ES complex is essential for catalysis and the enzyme is released unchanged
- B.The enzyme is permanently consumed in forming the product
- C.The EP complex is the most stable, long-lived state
- D.The substrate does not need to bind the active site
