Which of the following would you expect to happen to cellular respiration during exercise?
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.
B) Decreased 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 a decrease 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.
