Question

Which among the following is the fastest acting enzyme?

• A. Lipase
• B. Amylase
• C. Peptidase
• D. Carbonic anhydrase

Answer 1

The correct option is D Carbonic anhydrase

Carbonic anhydrase found in red blood cells is one of the fastest acting enzyme in biological kingdom. Carbonic anhydrase catalyzes the rapid interconversion of carbon dioxide and water to bicarbonate and protons (or vice versa), a reversible reaction that occurs relatively slowly in the absence of the catalyst.The reaction rate of carbonic anhydrase is one of the fastest of all enzymes, and its rate is typically limited by the diffusiion rate of its substrates. Typical catalytic rates of the different forms of this enzyme ranging between 10⁴ and 10⁶ reactions per second.
