Describe how facilitated diffusion affects free energy change compare to simple diffusion

Solutions

Expert Solution

generally In facilitated diffusion, the material first binds to the transport protein and then passes through the membrane. The concentration difference of the material being moved through the membrane is what causes the carrier protein to change its shape in facilitated diffusion.

example : sugar such as glucose can move from an areas where it has a high concentration to an area of low concentration by facilitated diffusion.

also the facilitated diffusion is a spontaneous process of passive diffusion of a molecule or ions across living membranes with the help of specific membrane integral proteins.

these proteins have two common features

they facilitate the net movement of solutes only in the thermodynamically favourable situations ( i.e delta G < 0 )
they show measurable affinity and specificity for the transported solute

in facilitated diffusion the free energy change when compared to simple diffusion because net movement of solutes happening only in thermodynamically favourable conditions so the free energy is less here when compared to simple diffusion
