Similarities: Both facilitated diffusion and active transport involve the movement of molecules across the cell membrane. They both require the presence of a protein channel or carrier to assist in the transport of molecules. Differences: Facilitated diffusion does not require energy and moves molecules along the concentration gradient, while active transport requires energy (ATP) and moves molecules against the concentration gradient. Energy is necessary for active transport because it moves molecules against their concentration gradient, which requires an input of energy. Facilitated diffusion moves molecules along the concentration gradient, which does not require energy. It is important for cells to move materials in and out to maintain homeostasis, acquire nutrients, remove waste, and communicate with other cells. This movement is essential for cell survival and function.
