In both lecture and lab, the significance of water (H2O), molecular oxygen (O2), and carbon dioxide (CO2) has been emphasized with regard to their energy content or participation in metabolic oxidation and reduction reactions. This lab has demonstrated that green leaf tissue shows both (A) photosynthetic light reactions and carbon fixation and (B) aerobic respiratory activities.

Describe how an increase in the carbon dioxide levels in the blood and interstitial fluid affects the heart, blood vessels, hemoglobin dissociation curve, and the respiratory system.
