Question

now that we can perform some experiments, which parameters could you use to measure the effect of exercise on cellular respiration in mice?
a) blood glucose concentration
b) all options
c) oxygen consumption
d) blood lactic acid concentration

Explanation:

• Blood glucose concentration: Glucose is the primary fuel for cellular respiration; exercise increases its use, so measuring this tracks substrate consumption for respiration.
• Oxygen consumption: Aerobic cellular respiration requires oxygen to break down fuel, so higher oxygen use indicates increased respiration rate during exercise.
• Blood lactic acid concentration: When exercise outpaces aerobic respiration, cells switch to anaerobic respiration, which produces lactic acid, so this measures anaerobic respiration activity.

All these parameters directly relate to measuring exercise's effect on cellular respiration in mice.

Answer:

b) All options
