Proteins are made up of sequences of amino acids. Amino acids are molecules made up of a amino group (NH3), a hydrogen (H), a carboxyl group ( O-C=O) and a variable group which varies among amino acids and defines the function of the amino acid.
No, proteins are biomolecules of cells. Whereas, cells are the unit of life. Cells are made up of lipids, proteins, and carbohydrates. And proteins are functioning in and out of cells.
No; cells are much larger. Cells contain a lot of protein.

No, cells are composed of all macromolecules: proteins, lipids, carbohydrates, and nucleic acids. Cells definitely contain protein in the membranes and organelles, but they're not wholly made up of protein or are a type of protein.
Ribosomes are the protein-building structures contained in all cells.Ribosomes
Prokaryotic cells have ribosomes, which is where protein synthesis occurs.
because of presence of RER
Nucleus.
Better question. What cells do not contain proteins? Proteins is from the Greek and means " first place, " so I can not think of any cell without some types of proteins.
microfilaments
Thrombocytes contain an occasionally active thrombin protein.
All cells contain proteins.
Red blood cells contain the protein hemoglobin, which binds with oxygen, and transport the oxygen throughout the body.
