But the secret of the magic percolator seemed to be selective permeability in the metal shell.

It is believed that claudin is the protein molecule responsible for the selective permeability between epithelial layers.

This potential is determined by the selective permeability of the cell membrane to various ions.

This characteristic is called selective permeability.

The selective permeability of the tubules is a major factor in this process.

A Calcium channel is an ion channel which displays selective permeability to calcium ions.

Due to the selective permeability of the phospholipid membraine only specific compounds can pass through it.

Also the selective permeability of the cell's plasma membrane for the different ions plays an important role.

He knew that all living cells had selective permeability to such things by nature of their chemical architecture.

The selective permeability of the cell wall is chiefly governed by pectins in the glycoprotein matrix.
