Question

Which of the following are examples of facilitated diffusion?

Answer 1

A. A chloride ion moves across the plasma membrane from a higher to lower concentration inside the cell.

Explanation:

Diffusion is the movement of particles from a region of higher concentration to that of lower concentration. Sometimes diffusion may require energy input to drive it.

• In facilitated diffusion, the concentration gradient creates the drive that fosters the diffusion.
• A membrane allows for the movement of tiny particles of matter across two regions.
• When the concentration in a region is above that of another, particles will move from the area having high concentration to that with a lower concentration till they both attain uniform concentration.
• This is known as facilitated diffusion.
