Microbiology Chapter 7

light energy absorption makes high-energy molecule that donates electrons to acceptor; ex- photosynthesis

High-energy food molecule donates electrons to acceptor

Organic molecules donates electrons to O2- Aerobic respiration

Organic molecule donates elctrons to itself or other molecule- not O2- Fermentation

Inorganic molecule donates electrons to O2- Ammonia Oxidation

Inorganic molecule donates electrons to other molecules- not O2; Methanogenesis

Energy is released when electrons move from molecules that have low affinity for electrons to molecules that have higher affinity for electrons (terminal electron acceptor)

Organic or Inorganic compounds

Oxygen

the relative affinity (difference) of the electron donor and receipients

A sequence of catalyized chemical reactions in a cell that are determined by enzymes

Glycolysis, Entner-Doudoroff, Pentase Phosphate

Produces 1 ATP, NADH, NADPH; runs on 3-5x less total protiens than glycolysis; most efficient in pace

in majority of organisms (humans); biosynthesis- builds nitronous bases

detecting amino acid catabolism using pH indicator (what type of metabolism is being used), detection of H2S using peptone iron agar, detecting protien catabolism using the urease test, fermentation test
