The type of membrane protein primarily involved in cell transport is: C. Integral proteins

Explanation:

Integral proteins (also known as transmembrane proteins) span the entire membrane and are crucial for facilitating the transport of molecules across the cell membrane. These proteins act as channels, carriers, or pumps that allow specific ions, nutrients, or other molecules to pass into or out of the cell. They play a key role in both passive transport (e.g., diffusion, facilitated diffusion) and active transport (e.g., ATP-driven pumps).

Other options:

A. Cholesterol molecules: Cholesterol molecules help maintain membrane fluidity and stability but are not directly involved ...
