BIOL 2051 : Exam 3 Part 1
Document Summary
Breaking down larger molecules into smaller molecules for energy. Break down large molecules in a series of steps coupled to reactions that store energy in small carriers such as atp and. Using energy to build cell components, more complicated molecules: metabolism. Central biochemical pathways used for both (amphibolic: tca 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. 2 state (amount of energy to get the reaction started: enzymes catalytic proteins that speed up biochemical reaction rates lower activation energy by bringing the substrates closer to each other and correctly orienting them. Active site/ catalytic site portion of an enzyme to which substrate binds. Substrate -----enzyme------ > product(s: fructose-1,6-bisphosphate -----aldolase enzyme---- > glyceraldehyde-3- phosphate + dihydroxyacetone phosphate. Very specific for their substrate [cellulose vs. starch example]
