This Class 11 Biology Chapter 9 Biomolecules NCERT Exemplar Book PDF is the official 2026-27 NCERT Exemplar, checked against the latest edition.

What the Biomolecules Exemplar Covers

The Exemplar tests the same chapter as the textbook but at a higher level of difficulty. Its questions probe common traps in the chemical composition of the cell, the structure of proteins, carbohydrates, lipids and nucleic acids, and the mechanism of enzyme action. Because Chapter 9 links chemistry to biology, the Exemplar spends its questions checking whether students can tell a primary metabolite from a secondary one, read the four levels of protein structure, and explain how an enzyme lowers activation energy.

• Analysis of chemical composition, primary and secondary metabolites and the idea of biomacromolecules.
• Structure of proteins, amino acids, polysaccharides, lipids and nucleic acids, with the primary to quaternary levels of protein structure.
• Enzymes and enzyme action, including cofactors, coenzymes, the effect of temperature and pH, and enzyme classification.

Why Practise the Exemplar for This Chapter

The Exemplar bridges the gap between the NCERT textbook and the level of a competitive exam. For biomolecules, its questions are close to the style asked in NEET and CUET, where a single detail about a peptide bond or the effect of pH on an enzyme can decide a mark. Because Chapter 9 mixes definitions with structures and mechanisms, the Exemplar is where students find the tricky assertion-reason sets and the well-framed MCQs that a plain reading of the textbook rarely throws up.

• Higher-order questions that the textbook exercises do not cover.
• Assertion-reason sets that sharpen your grip on protein and enzyme structure.
• MCQs on metabolites, bonds and enzyme kinetics at exam level.

How to Use the Exemplar for Biomolecules

Attempt the Exemplar only after you have finished the NCERT textbook chapter and its back exercises. Treat it as your second, harder pass over the chapter. Because much of this chapter is structure and mechanism, students gain the most by drawing each biomolecule and labelling its bonds rather than only marking the option, so the chemistry behind the biology stays fixed in memory for the exam.

• Solve the MCQs first to test recall, then move to assertion-reason.
• Attempt each short and long answer fully before checking the Exemplar Solutions.
• Mark the questions you got wrong and redo them after two days.
• Keep a chart of biomolecule types and their bonds handy while you practise.

Other Class 11 Biology Biomolecules Resources

Use the Exemplar with the textbook PDF, the solved answers, the revision notes and the formula sheet for the same chapter. Working across all the resources gives students the definitions, the practice and the higher-order questions they need for both the CBSE board exam and NEET.

Student Feedback on the Biomolecules Exemplar

More than 10,000 Class 11 students used these Collegedunia NCERT resources during the 2026 boards and NEET preparation. Their feedback shaped how we present this chapter, and the message on Chapter 9 was consistent: the Exemplar is what turns a chemistry-heavy chapter into exam-ready recall.

• Students rated the assertion-reason sets as the most useful part for fixing protein and enzyme structure.
• Many said the Exemplar MCQs on bonds and metabolites matched the NEET questions they later saw.
• Students preparing for CUET found the short-answer terms a fast way to revise the whole chapter.
