Selective Permeability
Description:
Selective permeability refers to the property of a cell membrane or a barrier that allows only certain substances to pass through while restricting the passage of others. It is a crucial mechanism for maintaining proper biological processes and regulating the transport of molecules within living organisms.
Sample Sentences:
- The cell membrane's selective permeability enables the passage of essential nutrients while preventing the entry of harmful substances.
- Due to its selective permeability, the blood-brain barrier acts as a protective shield for the brain, regulating the entry of molecules into this vital organ.
- The artificial membrane, designed with selective permeability, facilitates the separation of different compounds based on their size and properties.
- Scientists are studying the mechanisms underlying the selective permeability of cancer cells to develop targeted therapies.
