Terminal Respiration

Question 1

mitochondria is the only site of

Answer 1

oxidative phosphorylation

Question 2

oxidative phosphorylation allows the coupling of the oxidation of

Answer 2

carbon fuels to ATP synthesis

Question 3

for oxidation in the terminal respiratory system …….. and ……… have to be in the mitochondrial matrix

Answer 3

NADH

FADH2

Question 4

Glycerol phosphate shuttle

Answer 4

allows the NADH synthesized in the cytosol by glycolysis to contribute to the oxidative phosphorylation pathway in the mitochondria to generate ATP

Question 5

Electron transport chain

complex 1

Answer 5

oxidoreductase

oxidises NADH

passes high energy e-‘s to ubiquinone to give ubiqinol
