Our Biosphere has diversified living organisms where each organism has a different chemical composition and molecules inside them. And, this is what will be taught in the NCERT Solutions Class 11 Biology Chapter 9. Topics students will learn are How Chemical Composition in Living Organisms is Analyzed?, about Biomacromolecules, Primary & Secondary Metabolites, Polysaccharides, Proteins, Structure of Proteins, and Nucleic Acids.
Other topics that are included in this chapter and are relevant from the exam's perspective are What is the Nature of Bond that Links Monomers with Polymer, Dynamic State of Body Constituents, i.e. Metabolism Concepts, The Living State, Enzymes, and Metabolic Basis of Living. Let's briefly take a look at the topic taught in this chapter.
The presence of elements, like oxygen, carbon, hydrogen, etc., in living tissues per unit mass as regards to the earth's crust has been taught under this chapter. Coming under Unit III 'Structure and Functions of Cells' of class 11 Biology syllabus, this chapter takes students through the chemical composition of living cells, different chemical reactions and their conversions, nature of different enzymes actions, the role of enzymes, factors that affect the activities of enzymes, and how different enzymes are classified and named. This chapter promotes knowledge on the diversity of living organisms and how to develop a positive co-existence behavior with other living organisms.
