Question

Your friend makes a claim that the image to the right shows facilitated

diffusion. You are an educated Honors Biology student, and you believe
that he/she is incorrect in their claim. Make a claim as to which type of
cellular transport is represented in the image (1 point)State TWO pieces of
evidence from the image that supports your claim (2 points).*

Answer 1

Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.

Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.
