Concept explainers
To describe: The two ways in which integral proteins are associated with the plasma membrane.
Introduction: The fluid mosaic model describes the membrane as a phospholipid bilayer in which proteins are embedded to form a mosaic-like pattern. The bilayer ensures the separation of outer content from the content inside the cell. The membrane is semi-fluidic in nature, and the proteins, which are embedded within the membrane, are integral proteins.
To explain: The mechanism of the association of the peripheral proteins with the membrane.
