The lateral movement of transmembrane proteins can be restricted by several different mechanisms. Which mechanism best describes separating transmembrane proteins on the apical surface of the epithelial cells from their basal and lateral surfaces by limiting lateral movement of any transmembrane proteins?

(a) proteins are tethered to the cell cortex
(b) proteins are tethered to the extracellular matrix
(c) proteins are tethered to the proteins on the surface of another cell
(d) protein movement is limited by the presence of a diffusion barrier

The correct answer is option d, that is, the movement of protein is restricted by the existence of a diffusion barrier.

Explanation:

It is the organic behavior of the membrane that determines the solubility of the substances and the movement of proteins through the membrane. It is found that the spanning of the plasma membrane is done by some kind of diffusion barrier that restricts the movement of proteins through the membranes. This, in turn, limits unwanted molecules diffusion through the membrane.

yes it is   dangerous
