1Phototrophy
light energy absorption makes high-energy molecule that donates electrons to acceptor; ex- photosynthesis
2Chemotrophy
High-energy food molecule donates electrons to acceptor
3Organotrophy- AEROBIC
Organic molecules donates electrons to O2- Aerobic respiration
4Organotrophy- ANaerobic
Organic molecule donates elctrons to itself or other molecule- not O2- Fermentation
5Lithotrophy- AEROBIC
Inorganic molecule donates electrons to O2- Ammonia Oxidation
6Lithotrophy- ANaerobic
Inorganic molecule donates electrons to other molecules- not O2; Methanogenesis
7Oxidation-Reduction Reaction (Redox)
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)
8Where do the electrons source from in Redox reactions?
Organic or Inorganic compounds
9What is one of the best oxidizers?
Oxygen
10What is the amount of energy dependant in Redox reactions?
the relative affinity (difference) of the electron donor and receipients
11What is a metabolic pathway?
A sequence of catalyized chemical reactions in a cell that are determined by enzymes
12What are some Alternative Sugar Metabolism?
Glycolysis, Entner-Doudoroff, Pentase Phosphate
13Entner-Doudoroff Pathway
Produces 1 ATP, NADH, NADPH; runs on 3-5x less total protiens than glycolysis; most efficient in pace
14Pentose Phosphate
in majority of organisms (humans); biosynthesis- builds nitronous bases
15different types of Biochemical tests
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
