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. sort each of the phrases as describing flippases, floppases, or scramblases. choose the best, most-specific enzyme name. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more phrases are sorted incorrectly. not atp-dependent, activation may result in increased membrane lipid symmetry, abc transporter, translocate lipids from outer (extracellular) leaflet to inner (cytosolic) leaflet, translocate phosphatidylserine, preventing apoptosis and engulfment by macrophages, move phospholipids from inner (cytoplasmic) leaflet to outer (extracellular) leaflet, move phospolipids across the lipid bilayer down the concentration gradient
