Biomolecules
Every living cell is built from the same small set of chemical building blocks. This chapter in NCERT Class 11 Biology, Chapter 9, examines carbohydrates, lipids, proteins, nucleic acids, enzymes and water, and explains how structure shapes function. It shows how amino acids form proteins, how nucleotides build DNA and RNA, and how enzymes lower activation energy with specificity. You will learn tests for sugars and proteins, enzyme action, inhibition and why metabolism depends on precise molecular shape.
