Study the reaction given below

${\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O}\stackrel{\mathrm{Enzyme}}{\rightleftarrows }{\mathrm{H}}_2{\mathrm{CO}}_3$

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

1. Ribozyme

2. Carbonic anhydrase

3. Catalase

4. Peroxidase

All enzymes are proteins except

1. Trypsin

2. Pepsin

3. Steapsin

4. Ribozyme and Ribonuclease-P
