There are over 20,000 protein coding genes in the human genome. In addition many, perhaps most, of these genes can produce several different splice forms of protein, increasing the potential number of proteins manyfold. While no cell will express all possible proteins, they will at a minimum express several thousand of them. If you are looking for a specific protein, you need to provide more information.
Protein-cutting enzymes are made in the ribsomes of cells.
Hair is made of protein.
Yes, surface receptors are made of protein units in cells.
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.
No; cells are much larger. Cells contain a lot of protein.
No; cells are much larger. Cells contain a lot of protein.
No, cytoskeletons are made of protein filaments
Keratin
No, the liver is an organ made up of cells.
