Facilitated Diffusion — Definition & Types

Facilitated diffusion allows particles that can already easily cross the plasma membrane to cross it even more easily.

Facilitated diffusion allows particles to cross the membrane, without input of energy, that otherwise would not be able to without an input of energy.

Facilitated diffusion allows particles to flow against their concentration gradients.

Facilitated diffusion is the type of active transport that requires the least input of energy.
