Answer 2

Answer:

(C) 6 lakhs

Explanation:

• Carbonic anhydrase or CA is a vital enzyme that catalyzes the hydration and dehydration of CO₂.

• The reaction can be summarised as:

        CO₂  +  H₂O  ⇄  H₂CO₃ ⇄   H⁺ + HCO₃⁻ (Bicarbonate ion)

• This enzyme found in the Red blood cells (RBCs) catalyzes the hydration of CO₂ and forms Carbonic acid. This acid being unstable further dissociates into protons and bicarbonate ions representing the major transport mechanism of CO₂ in the blood of vertebrates.

• When we inhale oxygen, this oxygen diffuses into the blood, binds to the hemoglobin, and is transported in the body. So the Carbon dioxide diffuses out of the cells and tissues get transported through the blood as their carrier. When RBCs reach the lungs, these enzymes help in the conversion of bicarbonate ions to CO₂, which we exhale.

• This enzyme speeds up the rate of conversion to a millionfold and in every second around 6 lakhs of carbonic acid molecules are produced.

Hence Option (C) 6 lakhs is correct.
