Show Hint
To remember nitrogenous bases: Pure As Gold (Purines = Adenine, Guanine). Pyrimidines are CUT (Cytosine, Uracil, Thymine).

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Biomolecules are the organic molecules that make up living organisms. Let's evaluate each statement:
• Statement A is Incorrect: Lipids are water-insoluble (hydrophobic) molecules.
• Statement B is Correct: Proteins are linear chains of amino acids linked by peptide bonds, hence they are polypeptides.
• Statement C is Correct: Polysaccharides (like starch or cellulose) are polymers consisting of long chains of monosaccharides (sugars).
• Statement D is Incorrect: Adenine and Guanine are Purines (double-ring structures), not pyrimidines. Cytosine, Uracil, and Thymine are pyrimidines.
• Statement E is Correct: While some RNA molecules (ribozymes) act as catalysts, almost all enzymes are proteins. The correct statements are B, C, and E.
• Statement A is Incorrect: Lipids are water-insoluble (hydrophobic) molecules.
