Terminal Respiration Flashcards
mitochondria is the only site of
oxidative phosphorylation
oxidative phosphorylation allows the coupling of the oxidation of
carbon fuels to ATP synthesis
for oxidation in the terminal respiratory system …….. and ……… have to be in the mitochondrial matrix
NADH
FADH2
Glycerol phosphate shuttle
allows the NADH synthesized in the cytosol by glycolysis to contribute to the oxidative phosphorylation pathway in the mitochondria to generate ATP
Electron transport chain
complex 1
oxidoreductase
oxidises NADH
passes high energy e-‘s to ubiquinone to give ubiqinol
Electron transport chain
complex 2
succinate-Q reductase
oxidises FADH2
passes high energy e-‘s to ubiquinone to give ubiqinol
Complex 1
oxidoreductase
Complex 2
succinate Q reductase
electron transport chain
complex 3
cytochrome c oxidoreductase
takes the e-‘s (from ubiquinol) and passes them to cytochrome C
electron transport chain
complex 4
cytochrome c oxidase
takes the e-‘s from cytochrome C and passes them to molecular O2
complex 4
cytochrome c oxidase
complex 3
cytochrome c oxidoreductase
ATP synthase (ATPase) has 2 parts
F0 and F1
binding change mechanism
protons move from the positive side of the membrane to the negative side
conformational changes of the beta subunit
oxidation of FADH in terminal respiration generates less ATP than
NADH oxidation
