Key Syllabus Coverage (Official IGNOU MBC-005)

• Block-1: Carbohydrate Metabolism

  Detailed exploration of glycolytic pathways, gluconeogenesis, and the Pentose Phosphate Pathway, with emphasis on regulatory enzymes like Hexokinase, Phosphofructokinase, and Pyruvate Kinase. Includes metabolic interconnections with lipid and amino acid metabolism.

  • Mechanism and regulation of glycolysis in anaerobic vs. aerobic conditions
  • Role of Fructose-2,6-bisphosphate in metabolic control
  • Clinical relevance of Glycogen Storage Diseases (e.g., von Gierke’s, Pompe’s)

• Block-2: Lipid Metabolism and Associated Disorders

  Comprehensive analysis of fatty acid oxidation, ketogenesis, and lipid biosynthesis, including Triacylglycerol and Phospholipid metabolism. Discusses inherited disorders like Refsum’s Disease and LCAT Deficiency.

  • Enzymatic steps of Beta-Oxidation in peroxisomes vs. mitochondria
  • Regulation of Acetyl-CoA Carboxylase and Fatty Acid Synthase
  • Metabolic fates of Ketone Bodies in diabetes and starvation

• Block-3: Amino Acid Metabolism

  Focus on transamination, deamination, and the Urea Cycle, with emphasis on Essential vs. Non-Essential Amino Acids and their metabolic fates. Includes Phenylketonuria and Maple Syrup Urine Disease as case studies.

  • Role of Alanine and Glutamine in nitrogen transport
  • Regulation of Carbamoyl Phosphate Synthetase I in the urea cycle
  • Pathways of Tyrosine and Tryptophan metabolism

• Block-4: Nucleotide Metabolism

  Detailed breakdown of purine and pyrimidine biosynthesis, salvage pathways, and their integration with one-carbon metabolism. Covers Lesch-Nyhan Syndrome and Orotacyluria.

  • Enzymatic steps in De Novo Purine Synthesis (e.g., PRPP role)
  • Regulation of CPSase II in pyrimidine biosynthesis
  • Clinical implications of Hypoxanthine-Guanine Phosphoribosyltransferase (HGPRT) deficiency

Subject-Specific FAQs

• Q: How does glycolysis differ in muscle vs. liver cells?

  The liver expresses Glucose-6-Phosphatase, allowing gluconeogenesis, while muscle lacks this enzyme and relies solely on glycolysis for ATP production.

• Q: Why is acetyl-CoA a critical metabolic hub?

  Acetyl-CoA serves as the entry point for the TCA Cycle, fatty acid synthesis (via Citrate Shuttle), and ketogenesis, linking carbohydrate, lipid, and amino acid metabolism.
