Question

Quizplus · Accepted Answer

Active transport is the process by which cells move molecules against their concentration gradient, requiring the use of energy. In the small intestine, glucose and amino acids exist in lower concentrations in the intestine than inside the cells. Active transport allows the cells to take these nutrients up from the intestine into the bloodstream, providing necessary energy to the body.
