Vitamin C deficiency causes scurvy.

Conclusion – Part 19 (Biomolecules)

The Biomolecules chapter is one of the most straightforward and scoring sections in NEET Chemistry. Unlike many organic chemistry chapters that involve complex reaction mechanisms, biomolecules focus primarily on conceptual understanding of biological compounds, including carbohydrates, proteins, nucleic acids, and vitamins.

Practicing Part 19 helps students clearly understand the structure and function of important biomolecules. NEET questions from this chapter are often direct but require precise conceptual knowledge. Topics such as peptide bonds, reducing and non-reducing sugars, amino acid structure, enzyme function, and vitamin deficiency diseases frequently appear in the exam.

Another advantage of mastering biomolecules is that it requires logical understanding rather than heavy calculations or long reaction mechanisms. This makes it a high-return chapter during revision. Students who practice structured MCQs like those in Part 19 can quickly strengthen memory retention of key biomolecule properties and biological functions.

The questions in this practice paper also reinforce important concepts such as DNA vs RNA differences, storage polysaccharides, enzyme catalysis, and protein structure. These topics are repeatedly tested in NEET and are considered relatively scoring when students revise them regularly.

Overall, solving this paper improves speed, accuracy, and conceptual clarity, helping students confidently handle biomolecule-based questions in NEET. With consistent practice, this chapter becomes one of the easiest sections to secure marks and strengthen overall Chemistry performance.
