Verified step by step guidance

Understand the structure of the cell membrane: The cell membrane is primarily composed of a lipid bilayer with embedded proteins. These proteins can be classified as integral or peripheral based on their location and interaction with the lipid bilayer.

Differentiate between integral and peripheral proteins: Integral proteins are embedded within the lipid bilayer and can span the entire membrane, often functioning as channels or transporters for ions and molecules. Peripheral proteins, on the other hand, are not embedded within the lipid bilayer.

Identify the characteristics of peripheral proteins: Peripheral proteins are loosely attached to the surface of the membrane, either on the extracellular or cytoplasmic side. They may interact with integral proteins or the polar heads of lipids.

Consider the functions of peripheral proteins: While they do not span the membrane or form channels, peripheral proteins play roles in signaling, maintaining the cell's shape, and anchoring the cytoskeleton.

Review the options given in the problem: Evaluate each statement based on your understanding of peripheral proteins. The correct statement is that peripheral proteins are loosely attached to the surface of the membrane.
