Question

What type of transport proteins move solutes through cellular membranes without expending metabolic energy?

A) Active transporters

B) Facilitated diffusion proteins

C) Sodium-potassium pumps

D) Ion channels

Answer 1

Facilitated diffusion proteins are the type of transport proteins that move solutes through cellular membranes without expending metabolic energy.

Step-by-step explanation:

Facilitated diffusion proteins are the type of transport proteins that move solutes through cellular membranes without expending metabolic energy. These proteins work by allowing molecules or ions to move down their concentration gradient through specific transmembrane proteins or channels in the membrane.
