Biomolecule Classification and Overview
Get an overview of the major classes of biomolecules and their general properties.
Why this shows up in the exam
Basic classification is foundational and often tested as introductory questions.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Which of the following is correct?
Push further
More challenging5 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
Consider the following statements about biomolecules and organic compounds: I. All enzymes are proteins, but not all proteins are enzymes. II. DNA contains deoxyribose sugar and thymine base. III. Saponification is the hydrolysis of an ester in the presence of an acid catalyst. IV. Tertiary structure of proteins involves only hydrogen bonding.
