How does molecular size affect to the permeability
of the membrane to that molecules?
So you will try to find out how many
molecules of each kind pass through the membrane per time unit. If molecules
pass faster, it’s highly permeable to that material. Some molecules may not
pass at all, so then it’s not permeable to that material. Then you can put the materials
in order from the lowest to the highest permeability. You can also try to find
a mathematical formula that shows how permeability increases or decreases as size
increases (usually it decreases). Exel is usually helpful to find that formula:
you can make a plot and see if it is linear, exponential, potential, etc. There
are other softwares with a larger variety of graph options tan Excel.
Permeability is defined as the ability of the membrane or material to allow the passage of ions, molecules, and other substances.
The permeability is affected by the molecule size, molar mass, and polarity of the substance.
The investigative question is:
How does the size of the molecule affect the permeability of the membrane?
Permeability is the property of a membrane, which allows the molecules to diffuse through them. The permeability of the membrane is dependent on:
- Molecule size affects the permeability, such that smaller molecules diffuse easily than other large particles.
- Molar mass also affects the permeability, such that the higher the mass, the lower will be the diffusivity of the molecule.
- The polarity of the molecule also affects the permeability, for example, polar molecules and ions are unable to pass through the lipid membrane.
Therefore, permeability is affected by certain factors like molecule size and polarity.
