Question 12

Which of the following would you expect to happen to cellular respiration during exercise?

Accepted Answer

A)  Increased cellular respiration occurs during exercise, causing a rise in plasma PCO₂, which is detected by central chemoreceptors in the brain and perhaps peripheral chemoreceptors in the carotid sinus and aorta to cause an increase in respiration rate.

C)  Exercise causes a decrease in cellular respiration by shifting peripheral chemoreceptors in the heart to cause retention of oxygen. 
D)  Increased cellular respiration occurs during exercise, causing a decrease in plasma PCO₂, which is detected by central chemoreceptors in the brain and perhaps peripheral chemoreceptors in the carotid sinus and aorta to cause a decrease in respiration rate.
