Document Summary
If you need to miss a discussion section: notify your ta. If you can attend an alternate section, please email both the normal ta and the ta for the other section: send in the pre-lab discussion questions by the normal section time, might need to arrange meeting with ta. A reaction has a g of -5. 6 kcal/mol. Catabolic pathways yield energy (by oxidizing organic compounds) Anabolic pathways have chemical reactions which simpler substances are usually combined into more complicated molecules (use energy) Catabolic - release stored energy by breaking down molecules. Tricarboxylic acid cycle (tca cycle or citric acid cycle) 2 atp used for glucose, 4 atp formed. Pyruvate oxidation - catalyzed by pdh: decarboxylation, oxidation, acetyl-coa synthesis. 2 carbon + coa is fed into the cycle. Start with 6 carbons after 2 turns, all co 2 from initial glucose is used. G = -nf e n = number of electrons. F = faraday constant (charge of 1 mol electrons)
