Microbial Metabolism
Question | Answer |
---|---|
Catabolic Reactions | Is the breaking down of larger molecules into smaller ones, energy in ATP results from catabolic reactions |
Anabolic Reactions | building up of larger molecules from smaller molecules, generates material for cell growth |
Naming enzymes | named after the substrates it acts upon and ends with -ase |
intermediate | temporary form of the substrate bound to an enzyme at its active site |
Product | transformed substrate following the binding of an enzyme to the active site |
competitive inhibitor | fill the active site of the substrate so the enzyme cannot |
non-competitive inhibitor | binds to allosteric site, making the substrate change shape and become non functional |
feedback inhibition | when allosteric site is used to stop the formation of products to keep from having a excess |
1. Oxidative Phosphorylation | transfer of electrons through the electron transport chain system |
2. Glycolysis | breaking down of glucose into pyruvic acid |
3. Fermentation | releases energy from organic molecules, mostly aerobic, does not use Krebs cycle |
4. Pentose-Phosphate pathway | used in synthesis of nucleic acids, glucose from CO2 and amino acids |
