How do active transport and facilitated diffusion differ?

Question

a
one uses help from proteins and the other does not
b
one requires energy and the other does not
c
active transport moves molecules against a concentration gradient and facilitated diffusion does not
d
both b & c

Answer 1

d) both b & c

Active transport requires energy to move molecules across a membrane against their concentration gradient, while facilitated diffusion does not require energy and moves molecules along their concentration gradient. Additionally, both processes involve proteins, with active transport relying on transport proteins and facilitated diffusion using carrier or channel proteins.
