BIOL 2051 Study Guide - Quiz Guide: Pentose Phosphate Pathway, Pentose, Catabolism
Document Summary
Catabolic pathways breakdown large molecules in a series of steps coupled to reactions that. Metabolism: catabolism, anabolism, metabolism store energy in small carriers. Central biochemical pathways used for both (amphilbolic) Reduced geological compounds (rocks, inorganic compounds) (reduced) biological macromolecules (starch, fats) (energy source for animals) (first energy source) Fructose-1,6-bisphosphate glyceraldehyde-3- phosphate + dihydroxyacetone phosphate: very specific for their substrate. Cellulose vs. starch example the substrate: enzymes can have small non-protein molecules that help in catalysis but aren"t part of the enzyme or. Two types: prosthetic groups- bound tightly to their enzyme, usually covalently & permanently, coenzymes- loosely bound to their enzyme, may associate with different enzymes, usually. Example- heme group in cytochromes derivatives of vitamins. Catabolism: the microbial buffet: microbes have great catabolic diversity. Lithotrophy: inorganic molecules [ex using iron: organotrophy: organic molecules [ex: e. coli uses glucose] Phototrophy: use light energy to reduce compounds, then use these as electron donor. Electron acceptors: respiration: inorganic molecules [ex: oxygen in aerobic respiration]
