AThe rate at which blood glucose is consumed
BThe rate at which the stomach makes its acid
CThe rate at which bile salts leave the liver
DThe rate at which fats are stored as glycogen
Answer & Solution
Correct answer: A. The rate at which blood glucose is consumed
1. Fibre has more than one use in the diet.
2. It promotes regular bowel movement by adding bulk.
3. It also regulates the rate of consumption of blood glucose.
4. Fats are never stored as glycogen, since glycogen is a glucose polymer, so that option confuses two storage forms.
5. Fibre binds cholesterol in the small intestine, but the release of bile salts from the liver is not described as something it controls.
