Can proteins flip flop
WebDec 29, 2024 · Flippases are transmembrane proteins that facilitate movement of lipids across cellular membranes. Energy-independent flippases (also called scramblases) randomize the distribution of lipids across the bilayer by facilitating bidirectional movement of lipids between membrane leaflets. WebBoth lipids and proteins can flip-flop. C While lipids can rarely flip-flop, proteins cannot. D While proteins can flip-flop, lipids cannot. Medium Solution Verified by Toppr Correct option is C) The movement of a molecule from one surface of the biological membrane to the other is called the flip-flop movement or transverse diffusion.
