Question

Which of the following is incorrect concerning carbohydrate absorption?

a) Carbohydrates are broken down into glucose during digestion
b) Glucose is absorbed in the small intestine
c) Carbohydrates are absorbed unchanged in the stomach
d) Insulin facilitates glucose uptake by cells

Answer 1

The correct answer is c) Carbohydrates are absorbed unchanged in the stomach.

Step-by-step explanation:

The correct answer is c) Carbohydrates are absorbed unchanged in the stomach.

Carbohydrates are broken down into glucose during digestion, primarily in the small intestine where most of the absorption takes place. Glucose is absorbed in the small intestine through the epithelial cells. Insulin facilitates the uptake of glucose by cells. However, carbohydrates are not absorbed unchanged in the stomach. Instead, they undergo digestion in the mouth and small intestine before being absorbed as monosaccharides.
