Answer
C. Proteins allow certain substances to pass through the cell membrane.
Explanation
Proteins embedded in the cell membrane play a crucial role in its function. One of their primary functions is to facilitate the selective transport of substances across the cell membrane. Through mechanisms such as facilitated diffusion and active transport, these proteins allow necessary molecules like ions, nutrients, and other substances to move in and out of the cell, maintaining cellular homeostasis and function.
