Quizplus · Accepted Answer

Vitamin B₁₂ (also known as B12) is required for the production of red blood cells and proper nerve function. Pernicious anemia is caused by the absence of intrinsic factor, a protein necessary for the absorption of B12 in the small intestine. Without intrinsic factor, B12 cannot be properly absorbed and utilized by the body, leading to a deficiency and the development of pernicious anemia.
