Compare and contrast the processes of facilitated diffusion and active transport. What will be an ideal response?
Concepts to Consider: Facilitated diffusion always occurs along the concentration gradient
of the substance being transported, while active transport occurs against a concentration
gradient; facilitated diffusion does not require a direct expenditure of energy, but rather an
indirect expenditure, while active transport requires direct expenditure of energy in the form
of hydrolysis of ATP; both processes require the assistance of membrane proteins that act as
channels through which the molecules being transported will pass.
