Types Of Passive Transport That Enable Materials To Cross The Cell Membrane

Describe the three different types of passive transport that enable materials to cross the cell membrane. Be sure to include examples for each type.

Passive transport is the movement of atomic molecules and ions without the use of any form of energy output across a cell membrane. Entropy substitutes the energy that active transportation is accustomed to systems often grows in the long-run. Its rate is highly dependent on a cell membrane’s permeability consisting of mostly proteins and lipids (Lennarz & Lane, 2013, p. 45). One type of passive transport is diffusion, where the substances in question travel from an area with a high concentration to a lower one with the concentration gradient being the difference between these two localities. Filtration is another form of active transport where solute molecules and water moves across a given cell membrane in a cardiovascular system that utilizes its hydrostatic pressure. Osmosis, on the other hand, involves the transfer of water molecules right across a membrane that is ostensibly selectively permeable.
