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.
Globular Proteins
These special structures are called protein gates or protein channels. Water is able to diffuse through the cell membrane since it is a small molecule. However, there are channels called aquaporins that allow water to enter the cell. A glucose molecule cannot just diffuse into a cell. There are glucose channels on the surface of the cell membrane that bind glucose molecules and allow them to enter the cell.
mRNA travels to the ribosomes within the cell during the process of protein synthesis.
tRNA, or transfer RNA, originates from the nucleus of a cell during the process of protein synthesis.
A protein containing vesicle within a cell fuses with the cell membrane and ejects the protein is called exocytosis. A lysosome eats or ingests a bacterium is called phagocytosis.

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.
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
Globular Proteins
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.

a protein is too big to enter a cell on its own, therefore it requires carriers in order to do so. the carriers transport the protein in/out of the cell.
stuff outside the cell attaches to proteins to enter the cell
Protein Synthesis
the process that causes the water to enter and leave the cell is diffusion
Materials enter the cells cytoplasm via the process of endocytosis. Na, K, Ca, water etc are allowed to enter the cell. Waste products products through cellular processes is exited the cell via exocytosis.
