Consider the following analogy that is of appropriate scale to approximate the relative speed of phospholipid lateral movement: assume that a phospholipid molecule is the size of a ping-pong ball, approximately 4 cm in diameter. imagine that phospholipid molecules of this size were placed, tightly packed and wall to wall in a room that was 6 m x 6 m. if two neighboring phospholipids exchanged position once every 1 x 10–7 seconds, calculate how fast they would be moving, expressed in kilometers/hour. then calculate how long it would take for one phospholipid to move from one end of the room to another.
