post - test cell membrane and transport: learn how transporters keep cells healthy one more thing before you go... lets find out how much you learned about this topic! this will help us personalize your learning experience, and dont worry, it wont affect your grades. question 6 of 13 passive transport mechanisms, such as facilitated diffusion and simple diffusion, allow substances to cross the cell membrane: only when moving from an area of lower concentration to an area of higher concentration. by utilizing metabolic energy directly derived from atp hydrolysis. without direct cellular energy expenditure, typically following a concentration gradient.

Explanation:

Passive transport, like facilitated and simple diffusion, moves substances along a concentration gradient from high to low concentration without using cellular energy (ATP).

Answer:

Without direct cellular energy expenditure, typically following a concentration gradient.
