When explaining how carbon dioxide combines with water to form carbonic acid as part of an acid-base lecture, the faculty instructor emphasizes that which enzyme is needed as a catalyst for this reaction?

Carbonic anhydrase is the enzyme that convert the Carbon dioxide and water into carbonic acid.

Explanation:

When aqueous form of carbon dioxide reacts with water,it produces carbonic anhydrase which is  acidic.

The reaction is-

H₂O+CO₂⇒H₂CO₃

Carbonic acid is a volatile acid which play an important role in bicarbonate buffer system and thus it maintains acid base level.

Carbonic acid is a weak acid that form 2 type of salts that are carbonate and bicarbonate.

Carbonic acid causes dissolve of limestone.

It can't exist in pure form.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
