What enables absorption of b12 across small intestine wall?
Intrinsic factor, which is made in the stomach.
What will the Lack of intrinsic factor result in?
B. pernicious anemia.
A limiting nutrient is to ecosystem productivity as a limiting factor is to population?
growth rate
A nutrient that is scarce or cycle slowly through an ecosystem is called?
the substance is a limiting factor, but im not sure at all__________________________________________orLimiting nutrient- single nutrient that either is scarce or cycles very slowly, limiting the growth of organisms in an ecosystem.
If a nutrient is in short supply in an ecosystem how will it affect an organism?
Nutrients are essential for us to live. Without them, we would eventually die. When we are short of a nutrient, we would suffer from disorders associated with low intakes of that nutrient. For example, low iron intakes may mea one becomes anemic; low intakes of vitamin C can result in scurvy; and low intakes of vitamin D can result in rickets during development stages for children. Each nutrient has its deficiency. So, by eating a variety of foods to get all of the nutrients means we are getting what we need to stay healthy.
Aids in absorption of vitamin b12?
It is called intrinsic factor, which enables the absorption of B12. Intrinsic factor is found in the parietal cells (mucosa cells) of the stomach lining.
Which vitamin need instritic factor for stomach for absortion?
B12 is the vitamin that requires intrinsic factor for absorption. B12 is also known as cobalamin.
Where does the absorption of vitamin B12 occur?
The vitamin B12 is a very important nutrient; it lowers risk of stroke, heart disease, cancer, Parkinson's, and Alzheimer's disease. The vitamin begins to absorb in the mouth, in contrast to most nutrients.
Why do you need intrinsic factor?
Intrinsic factor or gastric intrinsic factor is a protein produced by the stomach. It is used to absorb vitamin B12 in the small intestine. When there is a deficiency of the Intrinsic factor, there is a deficiency in the absorption of B12 into the body and this leads to pernicious anemia.
What carrier protein is responsible for absorption of vitamin B12?
Intrinsic factor
What is the function of the intrinsic factor?
Intrinsic factor is necessary for the proper absorption of vitamin b12 which is necessary for red blood cell maturation, and therefore prevents pernicious anemia
What vitamin requires intrinsic factor in order to be observed?
B12
What enables absorption of b12 across small intestine wall?
Intrinsic factor, which is made in the stomach.
What stomach secretion is necessary for normal hemoglobin Production in RBC's?
Intrinsic factor is secreted by the parietal cells and is critical for absorption of B12. When the body attacks the parietal cells b12 deficiency results which is called "pernicious anemia."
When is vitamin B 12 poorly absorbed in the absence of?
Intrinsic Factor. This, also known as gastric intrinsic factor (GIF),isa glycoprotein produced by thestomach necessary for the absorption ofB12 there and in the small intestine.
What vitamin requires intrinsic factor in order to be bsorbed?
vitamine b12
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.
