Study the reaction given below CO 2 +H 2 O ⇌ Enzyme H 2 CO 3 ​In the absence of any enzyme, this reaction is very slow, with 200 molecules of H 2 CO 3 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.

Options

  1. ARibozyme
  2. BCarbonic anhydrase
  3. CCatalase
  4. DPeroxidase

Correct answer

B. Carbonic anhydrase

Step-by-step solution

The reaction catalyzed by carbonic anhydrase is: CO 2 + H 2 O ⇌ carbonic anhydrase H 2 CO 3 In the absence of any enzyme this reaction is very slow, with about 200 molecules of H 2 CO 3 being formed in an hour. However, by using the enzyme present within the cytoplasm called carbonic anhydrase, 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.
