E)ATPase

Question

Quizplus · Accepted Answer

The enzyme that catalyzes the first step reaction in HCl production by gastric parietal cells is carbonic anhydrase, which converts CO2 and H2O into H2CO3. This reaction is followed by a series of other reactions, ultimately leading to the production of HCl. Therefore, choice B, carbonic anhydrase, is the best answer.
