Study the reaction given below

${\text{CO}}_{\text{2}}{\text{+H}}_{\text{2}}\text{O}\stackrel{\text{Enzyme}}{\rightleftharpoons }{\text{H}}_{\text{2}}{\text{CO}}_{\text{3}}$

​In the absence of any enzyme, this reaction is very slow, with 200 molecules of H₂CO₃ formed in an hour. In the presence of an enzyme, the reaction speeds dramatically with about 600,000 molecules formed very second. Name the enzyme which has accelerated the reaction by 10 million times.
