Question

Quizplus · Accepted Answer

Pernicious anaemia develops from a deficiency of intrinsic factor, which is a glycoprotein produced by the parietal cells of the stomach. Intrinsic factor is necessary for the absorption of vitamin B12, and a deficiency of this vitamin can lead to pernicious anaemia. The other choices, ATP, carbonic anhydrase, and gastrin hormone, are not related to the development of pernicious anaemia.
