BIOL3200 EXAM 2 QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS GRADED A++ LATEST UPDATE
Heterotroph
use organic molecules as its carbon and energy source
Aubtotroph
uses CO2 as their carbon source, need a different energy source
Phototroph
Get their energy from light
Chemotrophs
use chemical compounds as energy source
lithotrophs
use inorganic molecules as a source of electrons
organotrophs
get electrons from organic molecules
3 common pathways to pyruvate
1. Embden-Meyerhof (glycolysis)
2.Enter-Doudorhoff (ED)
3. Pentose Phosphate (PPP)
glycolysis
the breakdown of glucose to pyruvate
Embeden-Meyerhof Pathway
, -occurs in the cytoplasmic matrix
-presence or absence of O2
-3 carbon and 6 carbon phase
-breakdown of glucose
STage 1 of EM
Energy investment
-Fructose 1,6 Biphosphate to DHAP and G3P
Stage 2 of EM
energy yeild
-DHAP has to become G3P the each G3P gets turned into pyruvate
-Redox reactions produce 2 molecules NADH
-4 ATP produced by substrate level phosphorylation (2 NET)
Fermentation
completion of catabolism without an electron transport chain
Glycolysis
A metabolic process that breaks down carbohydrates and sugars (glucose) through a
series of reactions to pyruvate and release energy for the body in the form of ATP.
Byproducts are 2NADH, 2 ATP, and 2 pyruvate.
Etc includes which 3 functional components
Oxidoreductase (dehydrogenase), a mobile elctron carrier, a terminal oxidase
optimum growth conditions
Sea level, temperature 200C-400C, neutral pH (around 7), less than 1% salt
extremophiles
