There are many uses for proteins in a cell membrane but the most common ones are:
1. Facilitated diffusion- a protein acts almost like a channel to allow molecules that cannot fit across the phospholipid bilayer to diffuse into/out of the cell
2. Active transport- proteins are used to move particles across the membrane from low to high concentration, using energy.
3. As receptor molecules which take signals from things like hormones.
Proteins are building blocks of the cells. It is needed to build new cells.

Ribosomes are the cell organelles that assemble proteins. They function as factories to produce usable proteins for a cell.
The proteins that control reaction in a cell are enzymes.

Proteins are made of amino acids, and created at ribosomes.

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.
Proteins are MUCH tinier (by a million times) than a cell.
Ribosomes produce proteins for the cell.
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.
