A group of BIOL 1114 students were able to measure various metabolic functions of a white mouse before and after they let it run on an exercise wheel for 10 minutes. You would correctly predict that the mouse would_______than before it ran on the exercise wheel a) move protons (H+) across the inner mitochondrial membrane faster b) make less metabolic H2O because fewer electrons will reach oxygen c) show a decreased rate of CO2 production d) pump more glucose out of the mitochondria e) pump more oxygen out of the mitochondria Solution a) move protons (H+) across the inner mitochondrial membrane faster During exercise, the metabolic rate increases, which results in more oxygen and glucose consumption. So, the metabolic water production and carbon dioxide production also increases. The protons move at a faster rate because the rate of metabolism increases during exercise..

1. A group of BIOL 1114 students were able to measure various metabolic functions of a white
mouse before and after they let it run on an exercise wheel for 10 minutes. You would correctly
predict that the mouse would_______than before it ran on the exercise wheel
a) move protons (H+) across the inner mitochondrial membrane faster
b) make less metabolic H2O because fewer electrons will reach oxygen
c) show a decreased rate of CO2 production
d) pump more glucose out of the mitochondria
e) pump more oxygen out of the mitochondria
Solution
a) move protons (H+) across the inner mitochondrial membrane faster
During exercise, the metabolic rate increases, which results in more oxygen and glucose
consumption. So, the metabolic water production and carbon dioxide production also increases.
The protons move at a faster rate because the rate of metabolism increases during exercise.
