Question

he picture shows the active transport of ions by the sodium-potassium pump. How is diffusion different from this process? A) Diffusion takes place due to osmotic pressure. B) Diffusion requires cellular energy for the transfer of molecules. C) Diffusion requires protein channels as a passage-way for particles. D) Diffusion transfers particles from an area of high to low concentration.

Answer 1

yes the answer is D.

Answer 2

Answer;

D) Diffusion transfers particles from an area of high to low concentration.

Explanation;

• Active transport is a physiological process that involves movements of molecules against a concentration gradient, and requires the use of energy in the form of ATP.
• Diffusion on the other hand involves the movement of particles or molecules from a region where they are in high concentration to a region where they are lowly concentrated.
• The two processes differ in the sense that diffusion is a passive transport where molecules move across the cell membrane through a concentration gradient while active transport requires cellular energy in the form of ATP for transportation of molecules against the concentration gradient.
