However, the cell regulates their distribution, rate of diffusion, multimerization, and assembly in the plasma membrane for ... axonal initial segment (IS) membrane. The barrier is formed in neurons 7 ...

Such essential molecules are moved across the membrane by special proteins called transport proteins or permeases. This process of forced diffusion of certain substances through the plasma ...

In both single-celled organisms like prokaryotic bacteria and eukaryotic algae, oxygen and carbon dioxide molecules move by diffusion through cell membranes. Larger multi-cellular organisms such ...
