NCERT Grade 11 Chapter 9, Biomolecules is a part of Unit 3, Cell: Structure and Functions. Unit 3 is a combination of 3 chapters and holds a total weightage of 9% in the NEET examination and 15 marks in the final examination. The concept of biomolecules will be introduced to the students giving it a physical and chemical perspective. What are biomolecules? How are they identified? Where are they found? What is the need to study biomolecules? These questions are answered in a very systematic and comprehensive manner in NCERT Grade 11 Chapter 9, Biomolecules.
All the carbon compounds that we get from living tissues can be called ‘biomolecules’, is a simple definition of biomolecules. Along with this, students shall learn How to Analyse Chemical Composition? Primary and Secondary Metabolites, Biomacromolecules, Proteins, Polysaccharides, Nucleic Acids, Structure of Proteins, Nature of Bond Linking Monomers in a Polymer, Dynamic State of Body Constituents - Concept of Metabolism, Metabolic Basis for Living, The Living State and Enzymes.
While learning about Enzymes; students will also be able to know Chemical Reactions, How do Enzymes bring about such High Rates of Chemical Conversions? Nature of Enzyme Action, Factors Affecting Enzyme Activity, Classification and Nomenclature of Enzymes and Co-factors. Although there is a bewildering diversity of living organisms, their chemical composition and metabolic reactions appear to be remarkably similar. This similarity can be easily drawn through in-depth study of NCERT Grade 11 Chapter 9, Biomolecules.
