question 21 (1 point) the difference between simple diffusion and facilitated diffusion is that facilitated diffusion moves materials from a lower to a higher concentration moves materials from a higher to a lower concentration requires transporter proteins requires atp does not require atp

question 21 (1 point) the difference between simple diffusion and facilitated diffusion is that facilitated diffusion moves materials from a lower to a higher concentration moves materials from a higher to a lower concentration requires transporter proteins requires atp does not require atp

Answer

Brief Explanations:

Simple diffusion is the passive movement of substances from high - to low - concentration without the help of proteins. Facilitated diffusion is also a passive process (no ATP required) but uses transporter proteins to move substances across the membrane.

Answer:

C. requires transporter proteins
