Facilitated diffusion is a type of passive transport that allows solutes to move

Question

Facilitated diffusion is a type of passive transport that allows solutes to move across the plasma membrane of a cell. Which statements describe facilitated diffusion? Solutes move down their concentration gradient directly through the plasma membrane without the use of energy. Solutes move across the membrane down their concentration gradient through specialized membrane proteins. Small, charged molecules and ions move down their concentration gradient into a cell through proteins in the plasma membrane. Membrane proteins use energy to move solutes across the membrane against their concentration gradient. Small, unchanged molecules move down their concentrating gradient out of a cell directly through the plasma membrane.
