Question

The following reaction is catalysed by CO2 + H2O + H2CO3
(A) Carbonic dehydogenase
(B) Carboxypeptidase
(C) Carbonic anhydrase
(D) Both A and B​

Answer 1

Explanation:

i think the answer is option a

Answer 2

The reaction CO2 + H2O ......> H2CO3 is catalysed by (c) carbonic hydrogenase.

• Carbonic dehydrogenase, Carboxypeptidase, Carbonic anhydrase all three contains zinc as metal.
• Carbonic dehydrogenase functions by maintaining acid-base balance, pH regulation and carbon dioxide transportation.
• Carbonic anhydrase help in the reaction of CO2 and H2O by increasing the rate of reaction. it also maintains pH by removal of CO2 at the lung surface.
• Carboxy peptide cleaves peptide bond (bond between amino acids).
