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

Question 9 options:

phospholipids and proteins are attracted to each other

phospholipids are attracted to each other by opposite charges

proteins attract each other with opposite charges

phospholipid molecules are not covalently bonded to each other

Solution

phospholipid molecules are not covalently bonded to each other

Phospholipids can move within the plane of the membrane. They are not covelently bonded giving the membrane fuid property. This allows proteins in the membrane to move laterally without rigidity.
