None of the molecules can be absorbed because they can’t cross the cell membrane without help. There aren’t transporters to carry them across

Step-by-step explanation:

Particularly important dietary carbohydrates include starch and disaccharides such as lactose and sucrose. None of these molecules can be absorbed for the simple reason that they cannot cross cell membranes unaided and, unlike the situation for monosaccharides, there are no transporters to carry them across
