Diffusing molecules move ________ until they are ________. Through channels of active transport proteins; evenly distributed up
koban [17]

Answer;

-Down the concentration gradients; evenly distributed

Diffusing molecules move down the concentration gradients until they are evenly distributed.

Explanation;

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.

-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.
