BCHET-149 IGNOU Handwritten Assignment 2026-27

Key Syllabus Units & Topics

• Cell Structure and Carbohydrates: Examines the role of carbohydrates as energy reserves and structural components, including monosaccharides, disaccharides, polysaccharides, and their metabolic pathways in cellular respiration and glycogenesis.
• Amino Acids, Peptides, and Proteins: Covers the 20 standard amino acids, peptide bond formation, protein structure (primary to quaternary), and functional diversity—highlighting enzymes, transport proteins, and structural proteins like collagen.
• Enzymes: Explores enzyme kinetics (Michaelis-Menten model), cofactors, allosteric regulation, and classification (EC numbers), with case studies on digestive enzymes (e.g., amylase, pepsin) and metabolic enzymes (e.g., hexokinase).
• Lipids and Nucleic Acids: Discusses lipid classes (fatty acids, phospholipids, steroids), membrane biology, and nucleic acid structure (DNA/RNA), including replication, transcription, and genetic code translation.
• Bioenergetics and Metabolism: Analyzes cellular respiration (glycolysis, Krebs cycle, oxidative phosphorylation), ATP synthesis, and anabolic pathways, with emphasis on energy balance and metabolic disorders.
