Cellular membranes are self-sealing— if they are punctured or disrupted mechanically, they quickly and automatically reseal. What properties of membranes are responsible for this important feature?

#Unit 2. Cellular Organization

The hydrophilic interactions among membrane lipids are noncovalent and reversible, allowing membranes to spontaneously reseal.
The hydrophobic interactions among membrane lipids are noncovalent and
reversible, allowing membranes to spontaneously reseal.
The hydrophobic interactions between membrane lipids and cholesterol are noncovalent and reversible, allowing membranes to spontaneously reseal.
