Describe metabolic acidosis

A) Metabolic acidosis occurs when pH decreases due to an impaired ability to remove CO2 by the lungs. B) Metabolic acidosis occurs when pH increases due to faster CO2 elimination by the lungs than production.

D) Metabolic acidosis occurs when pH increases due to the removal of hydrogen ions when bicarbonate ion concentrations are elevated. E) Metabolic acidosis occurs when pH increases due to an impaired ability to remove CO2 by the lungs.
