Proteins are so large that they require the interaction of vesicles on cell membranes to get out of cells. Some examples are; enzyme secretion, hormone secretion,neurotransmitter release. Basically they use vesicle formation to get transported into or out of the cell. And since vesicle forming is an energy requiring process it would be an exocytosis or endocytosis reaction.
But usually as an even simpler answer, cells do not usually take in proteins, they take in amino acids which then make their own proteins.

Are proteins assembled in the cell?
Ribosomes are the cell organelles that assemble proteins. They function as factories to produce usable proteins for a cell.
What are the proteins that control reactions in a cell?
The proteins that control reaction in a cell are enzymes.
What is a network of threadlike proteins in a cell?
a network of threadlike proteins within a cell
How the cell synthesizes proteins?
the ribosome makes proteins
Where in a cell makes proteins in an animal cell?
Proteins are made of amino acids, and created at ribosomes.
How are proteins trasported from the nuclear membrane to other parts of the cell?
the proteins travel through the cell by the endoplasmic reticulum(ER).
Where travel proteins?
Cellular (transported) proteins travels around the cell and sometimes destined to the particular organelle where it does its function. Secreted proteins such as albumin or hemogolbin are carrier proteins. Hemoglobin carries oxygen and carbon dioxide all over the body through blood tissue.
Are proteins assembled in the cell?
Ribosomes are the cell organelles that assemble proteins. They function as factories to produce usable proteins for a cell.
Is responsible for assembling proteins in the cell.?
Ribosomes are responsible for assembling proteins in the cell.Ribosomes are responsible for assembling proteins in the cell.
What are the proteins that control reactions in a cell?
The proteins that control reaction in a cell are enzymes.
What organelles produce proteins in the cell?
Ribosomes produce the proteins needed in a cell
What is a network of threadlike proteins in a cell?
a network of threadlike proteins within a cell
What cell builds lysosomes?
proteins
Cell part that produces proteins?
The part of a cell that produces proteins are the ribosomes. They are little circles that stick to the Rough Endoplasmic Reticulum and the chlorophyll. Ribosomes are actually proteins themselves.
How can proteins fit in the cell?
Proteins are MUCH tinier (by a million times) than a cell.
What produces proteins in an animal cell?
Ribosomes produce proteins for the cell.
Where are the ribosomes the manufacture proteins for transport out of the cell located?
Ribosomes which make extracellular proteins (proteins which are used outside of the cell) are located on the rER (rough ER). Ribosomes which make proteins which remain in the cell are free floating in the cell's cytoplasm.
