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; 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
A lipid bilayer does not contain a structural protein. Lipid bilayers are composed of lipids, such as phospholipids, arranged in a double layer that forms cell membranes and organelle membranes in cells. Structural proteins, on the other hand, provide support and shape to cells and tissues.
because of presence of RER
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.
Yes, feces can contain small amounts of protein from undigested food and cells shed from the intestines.
Prokaryotic and eukaryotic cells are similar in that they both contain DNA as their genetic material and have a cell membrane that encloses the cell. Both types of cells also contain ribosomes for protein synthesis.
No, not all living things contain cells. Viruses, for example, are considered living but are not made up of cells. They are instead composed of genetic material encased in a protein coat.
Thrombocytes contain an occasionally active thrombin protein.
All living cells contain both RNA and DNA. RNA is involved in gene expression and protein synthesis, while DNA stores genetic information. These molecules are essential for cellular function and replication.
