Question

a substance that moves  across a cell membrane without using the cells energy tends to move? a.)  away from the area of equilibrium b.) away from the area where it is less concentrated. c.) away from the area where it is more concentrated d.) toward the area where it is more concentrated

Answer 1

Answer: The correct option is C.) away from the area where it is more concentrated.

A substance that moves across a cell membrane without using the cells energy tends to move from an area of high concentration to an area of low concentration.

This is known as Passive transport. In this transport, substances move down the concentration gradient i.e from an area of high concentration to an area of low concentration. It is also called simple diffusion as no energy is required in this process.

Answer 2

C because this is passive transport and not using any energy. Passive transport is where a substance is moved from high concentration to low concentration.
