Final answer:
Phospholipids form the bilayer that is the foundational structure of cell membranes, providing a semi-permeable barrier and contributing to the overall function. The correct option is C.
Step-by-step explanation:
The component that is well-suited to its role in membranes is c) Phospholipids. Phospholipids form the phospholipid bilayer, which is the fundamental structure of cell membranes. This bilayer creates a semi-permeable barrier that protects the cell and controls the movement of substances into and out of the cell.
Other components such as carbohydrates play a role in adhesion and recognition, cholesterol contributes to membrane flexibility, and proteins, be they integral or peripheral, facilitate transport and serve as recognition sites, respectively.
