Multiple Choice

Which of the following statements about integral proteins in the plasma membrane is false?

Integral proteins are easily removed from the membrane without disrupting the lipid bilayer.

Integral proteins often have hydrophobic regions that interact with the lipid bilayer.

Integral proteins can function as channels or transporters.

Integral proteins span the entire lipid bilayer.

Verified step by step guidance

Understand the structure of the plasma membrane, which consists of a lipid bilayer with embedded proteins.

Recognize that integral proteins are embedded within the lipid bilayer and often span the entire membrane.

Note that integral proteins have hydrophobic regions that interact with the hydrophobic core of the lipid bilayer, making them difficult to remove without disrupting the membrane.

Identify the functions of integral proteins, which include acting as channels or transporters to facilitate the movement of substances across the membrane.

Evaluate the statement: 'Integral proteins are easily removed from the membrane without disrupting the lipid bilayer.' This is false because integral proteins are tightly associated with the lipid bilayer due to their hydrophobic interactions.
