What happens to carbon dioxide levels during a jog?

When you are jogging, your muscles are using more oxygen and releasing more carbon dioxide into the blood than when you are at home on the couch. Which of the following would occur during your jog? The medullary respiratory center would detect rising carbon dioxide levels.

Which has more alveolar surface area: frogs or mammals?

What would happen if hemoglobin was not carried by hydrogen ions?

acidic. If not carried by hemoglobin, hydrogen ions would reduce the pH, or increase the acidity, of the blood.

Which medium carries more oxygen?
