Which of the following processes requires BOTH a channel protein AND energy?

Question

Quizplus · Accepted Answer

Active transport requires both a channel protein and energy in the form of ATP to move molecules or ions against their concentration gradient. Facilitated diffusion also requires a channel protein, but it does not require energy as it moves molecules down their concentration gradient. Osmosis and simple diffusion do not involve channel proteins, as they occur across the phospholipid bilayer of the cell membrane.
