Question

Which of these statements describes what occurs in facilitated diffusion?-Facilitated diffusion requires energy from the cell to drive a concentration gradient.-Facilitated diffusion of solutes occurs through protein pores in the membrane.-Facilitated diffusion of solutes occurs through phospholipid pores in the membrane.-Facilitated diffusion is another name for osmosis.

Answer 1

Answer:

Facilitated diffusion of solutes occurs through protein pores in the membrane.

Explanation:

Facilitated diffusion: It is known as a type a passive transport which diffuses the solutes through specific trans membrane integral proteins in the plasma membrane. Transport proteins helps in diffuse some ions, and molecules across the plasma membrane.

There are three types of transport proteins which are involved in this diffusion:

1) gated channel proteins.

2) carrier proteins.

3) channel proteins.

Some example of facilitated diffusion are: glucose transporter, ion channels, and aquaporins.
