What enables absorption of b12 across small intestine wall?
Intrinsic factor, a protein produced by the stomach, is required for the absorption of vitamin B12 in the small intestine. In the small intestine, vitamin B12 binds to intrinsic factor, forming a complex that can be absorbed through the intestinal wall.
A protein secreted by the stomach that is necessary for the absorption of vitamin B12?
The protein secreted by the stomach that is necessary for the absorption of vitamin B12 is called intrinsic factor. Intrinsic factor binds to vitamin B12 in the small intestine, allowing for its absorption into the bloodstream. Without intrinsic factor, vitamin B12 cannot be effectively absorbed and can lead to a deficiency.
Which nutrient requires intrinsic factor for absorption?
Vitamin B12 requires intrinsic factor for absorption in the small intestine. Intrinsic factor is produced by the stomach and binds to vitamin B12 to facilitate its absorption in the ileum. Without intrinsic factor, vitamin B12 absorption is impaired, leading to deficiency.
What vitamin does Intrinsic factor facilitates its absorption from the small intestine?
Intrinsic factor facilitates the absorption of vitamin B12 from the small intestine. This glycoprotein, produced by the stomach's parietal cells, binds to vitamin B12, allowing it to be absorbed in the ileum. Without intrinsic factor, the body cannot effectively absorb vitamin B12, leading to deficiencies and associated health issues.
Aids in absorption of vitamin b12?
Intrinsic factor, a protein produced in the stomach, helps in the absorption of vitamin B12. This vitamin is crucial for red blood cell formation and neurological function. Absorption of vitamin B12 occurs in the small intestine, where it binds to intrinsic factor for transport into the bloodstream.
Which organ absorbs water and vitamin k from digested food?
The colon (large intestine) is responsible for absorbing water and vitamin K from digested food. Water absorption helps to form solid waste, while vitamin K absorption is important for blood clotting and bone health.
What substance is necessary for the absorption of vitamin b?
Intrinsic factor is the substance necessary for the absorption of vitamin B12. It is a glycoprotein produced by the stomach's parietal cells and is essential for the binding and absorption of vitamin B12 in the small intestine. Without intrinsic factor, the body cannot effectively absorb vitamin B12, leading to deficiencies. This is particularly important for preventing conditions like pernicious anemia.
What substance is essential for the absorption of vitiamin B-12?
Intrinsic factor is the essential substance for the absorption of vitamin B-12. It is a glycoprotein produced by the parietal cells in the stomach. Intrinsic factor binds to vitamin B-12 in the intestines, facilitating its absorption in the ileum, the last part of the small intestine. Without intrinsic factor, vitamin B-12 cannot be effectively absorbed, leading to potential deficiencies.
What role does the intrinsic factor play in the absorption of which nutrient?
The intrinsic factor plays a crucial role in the absorption of vitamin B12 in the small intestine.
How stomach helps in erythropoiesis?
parietal cells which can be found in gastric gland of stomach secretes intrinsic factor, which is a type of glycoprotein. this intrinsic factor, together with vitamin B12 is required for effective absorption of iron in small intestine. iron is required in erythropoiesis to produce haemoglobin. if iron absorption is low, RBC production will be affected. in summary, stomach helps in RBC production by producing intrinsic cells required in iron absorption.
What is absorption in shapes v functions of the skin?
Sensation Heat Regulation Absorbtion Protection Excretion Secretion Vitamin D
The absorption of which vitamin would be impaired by the removal of the stomach?
Vitamin B12 is released from proteins by concentrated levels of HCL acid in the stomach. Therefore, without the stomach there would be no HCL acid to release the B12
