Highly selective and saturated transport are not present in: (a) Active transport (b) Simple diffusion (c) Facilitated transport (d) Uphill transport
Option B. Facilitated transport or diffusion or passive-mediated transport can be defined as the process of spontaneous passive transport of molecules or ions across a cell membrane through the specific transmembrane integral proteins. It does not require the ATP molecules and is the diffusion is downhill.
