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. Suggest Corrections 2 Similar questions

WebQuestion: Lipids in a bilayer can diffuse laterally at a relatively fast rate, but "flip-flop" from one leaflet to the other very slowly without catalysis. Three protein families, flippases (or flipases), floppases, and scramblases, catalyze the movement of lipids across the bilayer. WebMar 24, 2024 · Complete answer: According to the fluid mosaic model of cell membrane proposed by Singer and Nicolson, due to the quasi-fluid nature of the lipids, the proteins in the membrane become able to move laterally within the lipid bilayer which is known as the fluidity of the membrane.
