In the process of diffusion,molecules move from areas where
A)their concentration is higher to areas where their concentration is lower until an equilibrium is reached.
B)their concentration is lower to areas where their concentration is higher until an equilibrium is reached.
C)their concentration is lower to areas where their concentration is higher through specific protein channels or carriers.
D)their concentration is higher to areas where their concentration is lower using energy from ATP.

Question

Quizplus · Accepted Answer

The process of diffusion involves the spontaneous movement of molecules from an area of higher concentration to an area of lower concentration until both areas reach an equilibrium. This occurs due to the random motion of molecules, with no external energy input required. Therefore, choice A is the correct answer. Choice B is incorrect because molecules do not move from areas of lower to higher concentration during diffusion. Choice C describes facilitated diffusion, which is a specific type of diffusion that involves the use of membrane proteins or carriers. Choice D describes active transport, which is a process that requires the input of energy (such as ATP) to transport molecules against a concentration gradient.
