Carbonic anhydrase is the best-known example ofa) Hydrolaseb) Transferasec) Lyased) Coagulative

Carbonic anhydrase is an enzyme that catalyzes the reversible conversion of carbon dioxide and water into carbonic acid, and vice versa. This process involves the hydration of CO2 to form H2CO3 (carbonic acid), and the enzyme plays a critical role in maintaining the acid-base balance in the blood and tissues.

To classify the enzyme, we need to look at its function:

Hydrolases are enzymes that catalyze hydrolysis reactions, where a water molecule is used to break bonds (e.g., breaking down proteins, fats, etc.).
Transferases transfer functional groups between molecules.
Lyases break chemical bonds by means other than hydrolysis or oxidation, often creating a double bond or ring structure.
Coagulative is not a correct category of enzymes.
Since carbonic anhydrase catalyzes a reversible hydration (addition of water) of CO2, it is classified as a Lyase enzyme.

Therefore, the correct answer is: c) Lyase
