H+ + HCO3- H2O + CO2 The equation above shows one of the reversible reactions that occur in blood. After exercise, an athlete’s blood pH has dropped below the normal level. How will normal blood pH be restored?

H+ + HCO3- H2O + CO2 The equation above shows one of the reversible reactions that occur in blood. After exercise, an athlete's blood pH has dropped below the normal level. How will normal blood pH be restored?

  • A An increase in O2 concentration in the plasma will lead to an increase in H+ concentration.
  • B An increase in temperature will lead to an increase in H+ concentration.
  • C An increase in sweating will lead to a decrease in OH- and H+ concentration.
