Biochemistry and Biotechnology for the Biology Olympiad

Explore essential biotechnology techniques and lab chemicals for the Biology Olympiad, including DNA transformation with calcium chloride and heat shock, gel electrophoresis, blotting, PCR, cloning, chromatography, and cell isolation.

Examine DNA and RNA analysis techniques, including northern blot for transcript abundance, PCR and RT-PCR for amplification and gene expression, and sequencing with gel and capillary methods.

Explore protein–DNA interactions with EMSA, DNA footprinting, and ChIP, highlighting cross-linking, immunoprecipitation, and downstream analysis by qPCR or sequencing.

Explore microscopy types, including light, fluorescence, and electron microscopes, with oil immersion and confocal imaging, plus methods like energy transfer and photobleaching to study living cells and protein interactions.

Explore thermodynamics, energy conservation, and entropy, and see how energy transforms from sunlight to chemical energy in photosynthesis. Understand oxidation–reduction and ATP’s role in anabolic and catabolic processes.

Explore how photosynthesis converts light energy into chemical energy by examining chloroplast structure, pigment absorption, paper chromatography of pigments, and the Calvin cycle.

Explore the light dependent reactions of photosynthesis, where water splitting at photosystem II releases oxygen, drives electron transport, builds a proton gradient, and yields ATP and NADPH through chemiosmosis.

Examine anaerobic respiration and fermentation, including ethanol and lactic acid pathways, then compare Cori cycle lactate shuttle with Cahill alanine cycle and their nitrogen waste like urea and uric acid.

Explore gluconeogenesis, the production of glucose from non carbohydrate substrates like lactate, glycerol, and glucogenic amino acids, mainly in the liver and kidney, for Biology Olympiad preparation.

Analyze fatty acid metabolism, focusing on beta oxidation and ketogenesis during fasting, producing ketone bodies for brain and muscle energy, and explore ketosis and ketoacidosis.

Explore solution chemistry, isomers, and bonds—from hydrogen to covalent bonds—and water properties, including acids and bases, condensation, hydrolysis, and essential Biology Olympiad formulas.

Explore the mass action law and equilibrium concepts, including reaction quotient Q versus K, and apply pH, acid-base definitions (Arrhenius, Bronsted-Lowry, Lewis), Ka, pKa, and buffers to biochemistry.

Discover how membrane lipids build the plasma membrane, from phospholipids and cholesterol to membrane proteins, and how tail length, saturation, temperature, and cholesterol regulate membrane fluidity.
