Suppose experiment was performed with the monosaccharide fructose instead of glucose. A beaker was filled with 30 ml of DNP + 15 mM fructose, and an everted intestinal sac was filled with Mammalian Ringers + 10 mM fructose. Predict the final concentration of fructose inside the sac after 1 hr incubation at 37°C.

Kaitlyn · Answer 1

greater than 10 mM.

Explanation:

This question deals with the transport of monosaccharide into the everted sacs of the intestine. And in order to be able to solve this question efficiently one must have prerequisite idea on the transport protein for the Sodium ion process of absorption. Also, one must know the structure of the epithelial.

What happens during the experiment is that there will be an absorption of the fructose, the Chloride ion and the Sodium ion and this absorption will lead to the production of osmotic gradient. Therefore, as the osmotic is produced, the fructose will be transported into the sac through diffusion and thus increasing the concentration of fructose.
