Document Summary
Food is broken down so you can use it as energy. Catabolic pathways breakdown large molecules in a series of steps coupled to reactions that store energy in small carriers such as atp and nadh: anabolism. Using energy to build cell components: metabolism. Central biochemical pathways used for both (amphibolic) Tca cycle (citric acid or krebs cycle), glycolysis, pentose phosphate shunt. Reduced geological compounds (rocks, inorganic compounds) (reduced) biological macromolecules (starch, fats) (energy source for animals) (first energy source) Catalysis and enzymes: activation energy: energy required to bring all molecules in a chemical reaction into the reactive state, enzymes: Catalytic proteins speed up biochemical reaction rates lower activation energy by bringing substrates into proximity to each other & correctly orienting them: active/catalytic site: portion of an enzyme to which substrate binds. enzyme. Fructose-1,6-bisphosphate glyceraldehyde-3- phosphate + dihydroxyacetone phosphate aldolase enzyme: Enzymes can have small non-protein that help in catalysis but aren"t part of the enzyme or the substrate.
