Flip-flop movement of proteins
WebSolution The correct option is D While lipids can rarely flip - flop proteins cannot The lipids in the bilayer can sometimes undergo transverse diffusion or "flip-flop movement" to go from one layer to the other. However, this does not occur with the proteins embedded in the bilayer.

FLIP is often used and is closely associated with Fluorescence recovery after photobleaching (FRAP). The major difference between these two microscopy techniques is that FRAP involves the study of a cell’s ability to recover after a single photobleaching event whereas FLIP involves the study of how the loss of fluorescence spreads throughout the cell after multiple photobleaching events. This difference in purpose also leads to a difference in what parts of th…
