active transport and facilitated diffusion are two types of cellular transport which statement is true of both
Dovator [93]

Answer:

I believe the correct answer is both involve proteins in the cell membrane.

Explanation:

This is because Facilitated diffusion does not require any energy to transport molecules, while Active transport requires ATP. Facilitated diffusion transports molecules from an area of higher concentration to an area of lower concentration (or down a concentration gradient). Active transport moves molecules from an area of lower concentration to an area of higher concentration (or up a concentration gradient). Answer choice A is the only choice that makes sense.
