Final answer:
The mucoprotein required for B12 absorption in the stomach is the intrinsic factor. It is a glycoprotein secreted by the gastric glands, crucial for the absorption of vitamin B12 in the small intestine.
Step-by-step explanation:
The mucoprotein in the stomach which is required for B12 absorption is known as intrinsic factor. This glycoprotein is secreted by the gastric glands and is essential for the absorption of vitamin B12 in the small intestine. In the presence of intrinsic factor, vitamin B12 can bind and be absorbed through the surfaces of the mucosal cells. Intrinsic factor is necessary because without it, vitamin B12 cannot be absorbed, leading to a deficiency that could impact red blood cell production and neurological functioning. Individuals who are unable to produce intrinsic factor may need to receive vitamin B12 injections to maintain adequate levels of this vital nutrient.
The mucoprotein in the stomach which is required for B12 absorption is intrinsic factor. Intrinsic factor is a glycoprotein that is secreted by the gastric glands in the stomach. It binds to vitamin B12 and helps in its absorption in the small intestine.
