Two cell membranes contain identical transport proteins but differ in phospholipid tail composition. Membrane Q has a higher proportion of saturated fatty acids; Membrane R has a higher proportion of unsaturated fatty acids. At the same temperature, lateral movement of membrane proteins is slower in Membrane Q than in Membrane R. Which membrane feature best explains the reduced protein mobility in Membrane Q? Which feature best explains the slower lateral movement of proteins in Membrane Q?
