Question

Quizplus · Accepted Answer

The force driving simple diffusion is the concentration gradient, which allows molecules to move from an area of higher concentration to an area of lower concentration without the need for energy. Active transport, on the other hand, requires energy to move substances against their concentration gradient, and this energy is often provided by ATP (adenosine triphosphate).
