1
Q
T he effect of exercise on breathing rate
A
Breathing rate increases to provide the body (exercising muscles) with oxygen at a higher rate. Heart rate increases to deliver the oxygen (and glucose) to the respiring muscles more efficiently
2
Q
with reference to cellular respiration, why breathing rate changes with and after exercise
A
Oxygen promotes cellular respiration no matter what we are doing; however, as the body demands more energy, the cells demand more oxygen. This demand for energy and oxygen is what causes your breathing rate to increase when you exercise.
