What property of the phospholipid bilayer allows proteins to move laterally in the membrane? (A). proteins attract each other with opposite charges (b). phospholipid molecules are not covalently bonded to each other. (C) phospholipids are attracted to each other by opposite charges

(b). phospholipid molecules are not covalently bonded to each other

Explanation:

Phospholipids are the structures which are typically made up of a phosphate group and lipid tails which are usually fluid. It should be noted that phospholipids are a regarded as a form of lipids i.e the molecules that are made up of hydrocarbons.

They're gotten from fatty acids and theyre vital components of the cell membrane. The property of the phospholipid bilayer allows proteins to move laterally in the membrane is that phospholipid molecules are not covalently bonded to each other. Some common phospholipids include phosphatidylcholine, phosphatidylinositol, etc.

Therefore, the correct option is B.

Correct
