Facilitated diffusion is a type of absorption that requires a special carrier to transport a molecule across the cell membrane and
a. requires energy.
b. does not require energy.
c. is also called pinocytosis.
d. is also called passive diffusion.
B
Facilitated diffusion allows absorption of molecules into cells from an area of low concentration to an area of high concentration; it uses a carrier protein but does not require energy. In pinocy-tosis a nutrient or liquid is engulfed by part of the cell membrane and taken into the cell in a va-cuole. Passive diffusion does not use a special carrier protein; nutrients pass from an area of high concentration to an area of low concentration.
