Membrane fluidity definition
Webmembrane fluidity The ability of lipid molecules to move sideways within their own single-molecule-thick layer. Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005 … WebThese kinks play a role in membrane fluidity because they increase the space between the phospholipids, making the molecules harder to freeze at lower temperatures. In addition, the increased space allows certain small molecules, such as CO 2 _2 2 start subscript, 2, end subscript and O 2 _2 2 start subscript, 2, end subscript , to cross the membrane quickly …
