Compare and contrast the processes of facilitated diffusion and active transport.
On Jul 03, 2024
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.
