What happens to pH and breathing rate during exercise? pH increases, which causes breathing rate to increase. pH decreases, which causes breathing rate to decrease. pH decreases, which causes breathing rate to increase. pH increases, which causes breathing rate to decrease.

Homeostasis: Respiratory & Blood pH Experiment: A person quickly runs up and down a set of stairs for 20 minutes. Their breathing rate is significantly increased during this time. Lots of ATP energy is needed for this activity which means lots of cellular respiration. 1. What waste gas product is accumulating in the bloodstream during the time of the exercise? CO2 2. What happens to the pH of the blood because of this? Decrease -> more acidic 3. For normal functioning, blood pH can only range from 7.35 to 7.45. What changes will you see in your body as you exercise vigorously for those 20 minutes? What other body systems are involved? 4. What is the stimulus for this feedback mechanism? 5. Name the effector for this feedback mechanism? 6. Would this be a negative or positive feedback mechanism? Why? 7. When does the feedback loop stop in this exercise example?
