Question

Quizplus · Accepted Answer

Vitamin B12 deficiency anemia is typically caused by a lack of intrinsic factor, which is necessary for the absorption of vitamin B12 from the gastrointestinal tract. Ferritin is a protein that stores iron and is not directly involved in the absorption of vitamin B12. Gastric enzymes and erythropoietin are also not directly involved in the absorption of vitamin B12.
