Chow_Kaitlyn_Block2_MM6
oxidation reduction reaction
oxidizing agent
donates electron
positive charge
oxidation (loss of e)
reducing agent
accepts donated electron
NAD+ (coenzyme)
traps glucose and organic molecules
negative charge
reduction (gain of e)
catabolic pathways
fermentation
degradation of sugars wo Oxygen
cellular respiration
glycolysis (step 1)
breaks glucose into two molecules (pyruvate)
in cytosol
citric acid cycle(step 2)
in mitochondria matrix
breaks glucose down by oxidizing pyruvate into CO2
electron transport chain(made of proteins)
oxygen and organic fuel used
types of fermentation
alcohol fermentation
pyruvate converted to ethanol
lactic acid fermentation
pyruvate reduced by NADH to form lactate
no CO2 released
free energy
change in G(free energy) =change In H(enthalpy) - T(temp) X change in S(entropy)
change in G= G final- G initial
part of system's energy that can do work when temperature and pressure are the same
reactions
exergonic
release of free energy
endergonic
take in free energy
enthalpy (total energy)
