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.
The process(s) by which large molecules enter a cell is/are diffusion and transport. It can be passive diffusion, or facilitated diffusion, or it can be active transport. The different processes used depend on several factors, such as lipid solubility of the molecule, presence or absence of specific transport proteins in the membrane, energy resources of the cell, etc.
A protein enters a cell through endocytosis.
facilitated diffusion
Facilitated Diffusion
diffusion
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.
to allow nutrient to enter for sustaining the cell; or to prevent bugs to enter
The lipid bylayer of the cell membranes is made of phospholipids which are hydrophilic heads and hydrophobic tails. The phospholipids are impermeable to ions such as salts, so the bilayer contains protein channels that allow the cell to regulate which molecules can enter the cell.
In the cell, the endoplasmic reticulum which contain ribosomes is the site for protein synthesis. Afterwards, the proteins undergo the translation process.
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 proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.

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.
the cell membrane allows what substance to enter the cells.
Protein Synthesis
stuff outside the cell attaches to proteins to enter the cell
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.
