Question

essential nutrients move through a cell membrane by both passive transport and active transport. which statement about active transport or passive transport is true?
passive transport requires chemical energy to move molecules into or out of the cell.
active transport allows molecules to diffuse through the membrane without the use of chemical energy.
passive transport moves molecules inside the cell from areas of low concentration to areas of high concentration.
active transport moves molecules across the cell membrane from areas of low concentration to areas of high concentration

Explanation:

Passive transport is the movement of molecules from high - to low - concentration areas without energy input. Active transport moves molecules from low - to high - concentration areas and requires chemical energy (ATP). Diffusion is a form of passive transport.

Answer:

D. Active transport moves molecules across the cell membrane from areas of low concentration to areas of high concentration.
