Fluctuations in hydrogen ions can cause various disorders in the body, except...

• increased excitability of the nervous system

• increased enzyme activity

• decreased activity of the central nervous system due to acidosis

• disrupting enzyme activity

• triggering hypokalemia due to alkalosis

The main role of the enzyme carbonic anhydrase in the blood buffer system is:

• Inhibit the formation of CO₂

• Inhibit the reaction between H₂O and CO₂

• Facilitate the conversion of CO₂ into carbonic acid

• Reduce bicarbonate levels

• Inhibit acid excretion in the kidneys
