Question

Which of the following statements is FALSE about PM structure?

a. the membrane is based on a lipid bilayer
b. the polar groups on membrane lipids are directed toward the aqueous environment
c. the hydrophobic groups on membrane lipids are directed toward one another
d. the membrane contains proteins
e. the membrane contains a double layer of proteins

Answer 1

The statement that is FALSE about phospholipid bilayer structure is that the membrane contains a double layer of proteins.

Step-by-step explanation:

The statement that is FALSE about phospholipid bilayer structure is: d. the membrane contains a double layer of proteins.

A phospholipid bilayer is the basic structure of the plasma membrane, consisting of two layers of phospholipids with their hydrophilic heads facing the aqueous external and cytosolic environments, and their hydrophobic tails interacting and facing each other in the interior of the membrane. Membrane proteins are embedded within the phospholipid bilayer, not forming a double layer themselves.
