Question

Study the reaction given below: 


In absence of any enzyme this reaction is very slow, with 200 molecules of H2CO3 being formed in an hour. In presence of 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


Solution

The correct option is B Carbonic anhydrase
Enzymes are bilogical catlysts which increase the rate of chemical reaction. The given reaction is catalysed by the enzyme carbonic anhydrase. By using the enzyme present within the cytoplasm, the reaction speeds dramatically with about 600,000 molecules being formed every second. The enzyme has accelerated the reaction rate by about 10 million times.
