Tamil Nadu HSE Second Year Biochemistry study guide
Tamil Nadu HSE Second Year Biochemistry · Work through your exam, one topic at a time.
The Tamil Nadu Higher Secondary Second Year Biochemistry course is the Class XII elective taken by students who have chosen the science stream with biochemistry, typically alongside chemistry, botany, zoology or microbiology. It is a school-examined subject: the theory paper is set and valued under the state higher secondary system, while the practical work and internal assessment are conducted by the school itself and carry marks that count toward the final grade. The Tamil Nadu HSE Second Year Biochemistry study guide has 10 sections and about 3,108 words.
01Biomolecules: Carbohydrates, Lipids, Amino Acids, Proteins and Nucleic Acids
Biomolecules questions ask you to classify carbohydrates, lipids, amino acids, proteins, and nucleic acids, then link structure to function and to simple chemical tests. Monosaccharides are polyhydroxy aldehydes (aldoses) or ketones (ketoses).
322 words, about 2 min02Enzymes: Classification, Kinetics, Inhibition and Regulation
Enzymes questions test the six IUBMB classes, active-site specificity, Michaelis-Menten kinetics, inhibition patterns, and physiological regulation. Six classes: oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases.
277 words, about 1 min03Bioenergetics and Biological Oxidation: ATP, Electron Transport Chain and Oxidative Phosphorylation
Bioenergetics questions ask how redox energy becomes ATP, how the electron transport chain is organized, and how inhibitors or uncouplers change oxygen use and phosphorylation. ATP is the main energy currency.
332 words, about 2 min04Carbohydrate Metabolism: Glycolysis, TCA Cycle, Gluconeogenesis and HMP Shunt
Carbohydrate metabolism questions test glycolysis, the TCA cycle, gluconeogenesis, and the HMP shunt, including locations, net yields, irreversible steps, and regulation. Glycolysis converts glucose to two pyruvate in the cytosol.
304 words, about 2 min05Lipid Metabolism: Beta-Oxidation, Ketogenesis, Cholesterol and Lipoproteins
Lipid metabolism questions test fatty acid activation and beta-oxidation, ketone body formation, cholesterol synthesis, and lipoprotein transport. Fatty acid activation to fatty acyl-CoA costs 2 ATP equivalents.
303 words, about 2 min06Amino Acid and Protein Metabolism: Transamination, Urea Cycle and Nitrogen Balance
Amino acid and protein metabolism questions test transamination, ammonia handling, the urea cycle, and nitrogen balance. Transamination transfers an alpha-amino group to an alpha-keto acid.
306 words, about 2 min07Nucleic Acid Metabolism and Molecular Biology: Replication, Transcription, Translation and Gene Expression
Molecular biology questions test DNA replication, transcription, translation, and gene expression, especially directionality, enzymes, and the genetic code. Replication is semiconservative and bidirectional.
310 words, about 2 min08Vitamins, Minerals and Nutrition: Deficiency Diseases and Dietary Requirements
Nutrition questions test fat-soluble and water-soluble vitamins, specific deficiency diseases, mineral functions, and dietary requirement terms. Fat-soluble vitamins A, D, E, K are absorbed with lipids; malabsorption causes multiple deficiencies.
308 words, about 2 min09Hormones and Metabolic Integration: Insulin, Glucagon, Thyroid and Steroid Hormones
Hormone questions test the actions of insulin, glucagon, thyroid hormones, and steroid hormones, and how they integrate fuel use in fed and fasting states. Insulin is made by pancreatic beta cells.
309 words, about 2 min10Clinical Biochemistry and Diagnostics: Blood and Urine Analysis, Liver and Kidney Function and Diabetes Markers
Clinical biochemistry questions test blood and urine analysis, liver and kidney function tests, and diabetes markers, with emphasis on choosing and interpreting the right test. Plasma glucose is preferred over serum for glucose because glycolysis continues in serum unless fluoride is added.
