Botany - Biomolecules (B)

Practise 23 AIIMS previous year questions on Biomolecules (B), compiled from papers spanning 2002 to 2018. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AIIMS tests.

Biomolecules (B) has been asked in 12 of the 19 years of AIIMS papers analysed (2001–2019), with 23 questions in all. 57% of them were easy, 22% moderate and 22% tough. Most of its questions came from 2015, with 3 questions that year. In the last three years (2017–2019) it had 4 questions across 5 papers, about 0.8 per paper.

The chapter's 7 topics are not weighted equally: Enzymes (10 questions, 43%), Primary and Secondary Metabolites (5 questions, 22%), and Lipids (4 questions, 17%) have been asked the most. Enzymes has produced the most tough questions (3).
