Verified step by step guidance
1
Understand the structure of the cell membrane, which consists of a phospholipid bilayer with embedded proteins.
Differentiate between the types of membrane proteins: integral, peripheral, lipid-anchored, and transmembrane proteins.
Recognize that integral proteins, including transmembrane proteins, are embedded within the lipid bilayer and often span the entire membrane, making them difficult to remove without disrupting the membrane.
Identify peripheral proteins as those that are attached to the exterior or interior surfaces of the membrane, often through interactions with integral proteins or the lipid bilayer, and can be removed without disrupting the membrane's integrity.
Conclude that peripheral proteins can be removed more easily compared to integral or lipid-anchored proteins, as they do not penetrate the hydrophobic core of the membrane.
