Question
Carbonic anhydrase is an enzyme which can convert carbon dioxide (CO2) and water (H20) to carbonic acid (H2CO3). Given what you know about enzymes, what is most likely to be true of carbonic anhydrase? O It lowers the activation energy required to form carbonic acid from carbon dioxide and water. It probably operates optimally at a pH close to the body's pH. It probably operates optimally around 37 degrees Celsius. It can convert CO2 and H2O to H2CO3 or it can convert H2CO3 to CO2 and H20 depending on whether there are more of the products or more of the reactants. All of the above.

Q7.
All of the above is the correct answer.
Becuase carbonic anhydrase during respiration which convert carbon dioxide and water to bicarbonate ions can also reverse the reaction depending upon the condition and concentration of amount.
If the temperature of the body increases then the activity of carbonic anhydrase also increases during exercise. Therefore it works optimally at normal body temperature.
Moreover if the pH of the blood increases to 8 or decrease(original 7.4) then its activity will decrease because maximum enxzymes work at normal or optimal pH else the carbonic anhydrase will be denatured.
