That's Correct!
It's Wrong!
Lipids are absorbed in the gastrointestinal tract through passive diffusion. Passive diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration without the need for energy. In this case, lipids move across the cell membranes of the gastrointestinal tract down their concentration gradient, allowing them to be absorbed into the body.
