Consider the equilibrium established in the carbonic acid-bicarbonate buffer system, which maintains pH balance in

mammalian blood:H2CO3 ? HCO3- + H+ During hypoventilation, breathing rate decreases, and therefore elimination of CO2 during exhalation decreases. How is optimal blood pH maintained when acid levels increase in our blood from hypoventilating?

a. excess H+ from the acid react with H2CO3 to decrease pH level b. excess H+ from the acid react with H2CO3 to increase pH level c. excess H+ from the acid react with H2CO3 to maintain pH level d. excess H+ from the acid react with HCO3- to increase pH level e. excess H+ from the acid react with HCO3- to maintain pH level
