Chemistry - Biomolecules

Practise 55 TS EAMCET previous year questions on Biomolecules, compiled from papers spanning 2008 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty TS EAMCET tests.

Biomolecules has been asked in 16 of the 24 years of TS EAMCET papers analysed (2001–2024), with 55 questions in all. 51% of them were easy, 40% moderate and 9% tough. Most of its questions came from 2020, with 8 questions that year. In the last three years (2022–2024) it had 14 questions across 17 papers, about 0.8 per paper.

The chapter's 8 topics are not weighted equally: Properties and Preparation of Amino Acids (11 questions, 20%), Disaccharides and Polysaccharides (10 questions, 18%), and Preparation and Reactions of Glucose (10 questions, 18%) have been asked the most. Properties and Preparation of Amino Acids has also led over the last five years, with 5 questions. Properties and Preparation of Amino Acids has produced the most tough questions (2).
