Facilitated diffusion and active transport both a. require ATP. $b$. require the use of proteins as carriers. c. carry solutes in only one direction. $d$. increase without limit as the solute concentration increases. $e .$ depend on the solubility of the solute in lipid.
Added by Paul M.
Step 1
Facilitated diffusion does not require ATP, while active transport does. So, this option is incorrect. $b$. Both facilitated diffusion and active transport require the use of proteins as carriers. So, this option is correct. c. Facilitated diffusion can carry Show more…
