Which of the following criteria dows not pertain to facilitate transport?

  • Requirement of special membrane proteins

  • High selectivity

  • Transport saturation

  • Uphill transport

Answer

D.

Uphill transport

Facilitated transport is a form a passive transport in which materials are moved across the plasma membrane by a transport protein down. Their concentration gradient. It requires integral membrane proteins and highly selective biological membranes to cross.
Saturation occurs in facilitated, diffusion because not enough carriers may be available to handle all the free solute molecules. The rate of movement may reach a maximum. Uphill transport is a process in which diffusion of a component occurs from a less concentrated permeable stream.
