protein
The cell must use a process called endocytosis to allow the large protein to enter. This process involves the cell membrane engulfing the protein and forming a vesicle that brings it inside the cell. Endocytosis is necessary for large molecules, like proteins, because they cannot pass through the lipid bilayer of the cell membrane due to their size and polarity. Once inside, the protein can be utilized for various cellular functions.
facilitated diffusion
Water soluble molecules often enter or exit a cell through a process called facilitated diffusion. This process involves the movement of molecules across the cell membrane with the help of specific protein channels or carriers.

The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.

Simple diffusion.
Channel proteins facilitate the passive movement of molecules down their concentration gradient. They form channels across the cell membrane, allowing specific molecules to move in and out of the cell without requiring energy input. This process is known as facilitated diffusion.
