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. Central biochemical pathways used for both (amphibolic) Reduced geological compounds (rocks, inorganic compounds) (reduced) biological macromolecules (starch, fats) (energy source for animals) (first energy source) Active site/ catalytic site portion of an enzyme to which substrate binds. Fructose-1,6-bisphosphate -----aldolase enzyme---- > glyceraldehyde-3- phosphate + dihydroxyacetone phosphate. Example- heme group in cytochromes loosely bound to their enzyme: may associate with different enzymes usually derivatives of vitamins. Enzymes are named either for the substrate they bind or for the chemical reaction they catalyze with the addition of the suffix ase . Hydrolases break various chemical bonds with the addition of water. Catabolism: the microbial buffet: microbes have great catabolic diversity. Phototrophy: use light energy to reduce compounds; use these as electron donors.
