Question

BlackTom AI · Accepted Answer

The question asks you to classify the type of membrane protein shown for protein C within a phospholipid bilayer.
First, recall the two main groups: integral (intrinsic) proteins, which are embedded in the lipid bilayer and often span the membrane, and peripheral (extrinsic) proteins, which associate with the membrane surface rather than penetrating the hydrophobic core.
In the diagram, protein C is drawn as a structure that sits within the hydrophobic core of the bilayer and appears to extend across or through the membrane, indicating it is embedded rather than merely attached to the surface.
If a protein were peripheral, you would expect it to lie on one face of the bilayer or be attached to an integral protein or lipid without crossing the hydrophobic interior.
Therefore, the characteristic that stands out for protein C is its integration into the membrane rather than a surface association, aligning with the properties of integral membrane proteins.
This interpretation aligns with standard descriptions of transmembrane or embedded proteins in a phospholipid bilayer.
