What property of the phospholipid bilayer allows proteins to move laterally in the membrane?

Question

Quizplus · Accepted Answer

Phospholipid molecules in the bilayer are not covalently bonded to each other, allowing for lateral movement of proteins within the membrane. This property is known as fluidity. Choice A is incorrect because it refers to protein-protein interactions, which are not the main driving force for lateral movement. Choice C is incorrect because although phospholipids have polar head groups that can interact through electrostatic interactions, these interactions do not significantly contribute to lateral movement.
