Question

Which of the following statements regarding absorption of

monosaccharides is true?
chose the correct answer:
subject name : nutrition



A)All monosaccharides require energy for absorption; therefore,

Answer 1

Monosaccharides are absorbed in the small intestine using different mechanisms, including active transport for glucose and galactose, and facilitated diffusion for fructose.

Step-by-step explanation:

Monosaccharides like glucose and galactose are absorbed via secondary active transport linked with sodium ions and then passively via facilitated diffusion. On the other hand, fructose absorption occurs only through facilitated diffusion, which does not require energy. These processes take place in the small intestine, enabling efficient absorption of carbohydrates digested from food into monosaccharides.

A direct answer to the question is that not all monosaccharides require energy for absorption; glucose and galactose require energy for active transport, while fructose does not.
