Passive transport is the diffusion of substances across a membrane. This is a spontaneous process and cellular energy is not expended. Molecules will move from where the substance is more concentrated to where it is less concentrated.
Thus, it requires energy. Whereas facilitated diffusion is a passive process and does not require energy. Active transport uses carrier proteins. Energy is used to change the shape of the carrier protein. Facilitated diffusion uses both gated channel proteins and carrier proteins in transport. Diffusion can be broken down into two things; simple and facilitated diffusion. Both simple and facilitated diffusion move from HIGH to LOW concenctration and NO ENERGY is needed for these and are called passive transport because no energy is needed.
