Which of the following vitamins requires an intrinsic factor for its absorption?Question 39Answera.Folateb.Vitamin Cc.Vitamin Ad.Vitamin B12

The vitamin that requires an intrinsic factor for its absorption is Vitamin B12.

Here's a step-by-step explanation:

1. Intrinsic factor is a glycoprotein produced by the parietal cells of the stomach.

2. It is necessary for the absorption of vitamin B12 later on in the ileum of the small intestine.

3. In the stomach, intrinsic factor binds with vitamin B12, preventing its digestion by stomach acid and protecting it from being destroyed in the earlier stages of digestion.

4. When the stomach content reaches the ileum, the cells lining the ileum have receptors that can pick up the Vitamin B12-Intrinsic factor complex.

5. Once the complex is absorbed by the ileum cells, Vitamin B12 can then be used in the body.

So, the answer is d. Vitamin B12.
