Metabolic decomposition reactions that BREAKDOWN large molecules into smaller molecules, usually with the net RELEASE of energy. 5 cofactors: Tender Loving Care For Noone (Thiamine, Lipoic acid, CoA, FAD, NAD). glycolysis, TCA cycle, HMP, EMP, Nitrogen fixation and DNA replication in microbes, first set of reactions in cellular respiration during which 1 molecule of glucose, a 6-carbon compound, is transformed into 2 molecules of pyruvic acid, a 3-carbon compound, provides source of NADPH from an abundantly available G6P (NADPH is required for reductive rxns, e.g, glutathione reduction inside RBC), glucose to pyruvate using different enzymes than glycolysis. MCQ 10: Viruses (Virology) @. 90 terms. When a system changes from a well-defined initial state to a well-defined final state, the Gibbs free energy ΔG equals the work exchanged by the system with its surroundings, minus the work of the pressure forces, during a reversible transformation of the system from the same initial state to the same final state.[2]. Signal propagation is terminated when the α subunit hydrolyzes GTP to GDP and reassociates with the βã subunits. Nitrogenase is inactivated by oxygen, so the heterocyst must create a microanaerobic environment. Human Physiology 101 (BIOL 1050) Academic year. Surplus of fixed N or in starved cells-nitrogenase not needed. ..., sulfate is reduced by plants and bicrobes for use in amino acid and protein biosyntesis, Key enzyme in assimilatory sulfate reduction, enzyme that methylates newly synthesized DNA strands and are involved in mismatched repair. lactic acid is made from pyruvic acid, no gas made in process, production of lactic acid, A pathway in which pyruvic acid is directly converted to lactic acide using electrons form reduced NAD. 1 of the key steps to regulating glycolysis; inhibited by ATP and activated by ADP; phosphoylated fructose-6-phosphate to fructose-1,6-phosphate. Features. This is the main regulatory step of glycolysis. CsrA is a regulator of carbohydrate metabolism that affects glycogen biosynthesis, glycogen degradation, gluconeogenesis , and glycolysis. 1. A common intermediate in the conversion of glycerol and lactate to glucose is what? Flashcards. You have free access to a large collection of materials used in college-level introductory microbiology courses (8-week & 16-week).The Virtual Microbiology Classroom provides a wide range of free educational resources including PowerPoint Lectures, Study Guides, Review Questions and Practice Test Questions. a short segment of DNA synthesized on a template strand during DNA replicating. Microbiology protein secretion. lactic acid fermentation, 3 products, only 1 ATP per glucose, glucose--> CO2, acetaldehyde, pyruvate, a metabolic pathway that generates NADPH and five-carbon sugars such as ribose 5-phosphate from glucose 6-phosphate; also refered to as hexose monophosphate shunt and the phosphogluconate pathway / it includes oxidative reactions which produce NADPH and ribose 5-phosphates as well as nonoxidative reactions which together convert five-carbon sugar phosphates to gluconeogenic precursors of glucose 6-phosphate, 1:The Bifidobacteria use a unique pathway of hexose catabolism, which produces primarily acetate and lactate. Its a cycle reaction that uses ATP. A futile cycle, also known as a substrate cycle, occurs when two metabolic pathways run simultaneously in opposite directions and have no overall effect other than to dissipate energy in the form of heat. Conversion of nitrates into nitroge…, The oxidation of ammonium to nitrate by chemolithotrophs. The use of sulfate as a terminal electron acceptor (sulfate is the oxidized form of sulfur). It looks like your browser needs an update. 26 terms. Learn microbial physiology with free interactive flashcards. The Gibbs free energy is the maximum amount of non-expansion work that can be extracted from a closed system; this maximum can be attained only in a completely reversible process. In the process, a carbon is lost in the form of carbon dioxide, and an NADH is formed. Produces the second ATP made in glycolysis. Microbial Metabolism and Enzymes.
