6 Proteins

7 Proteins Proteins are biomolecules which do everything in the cell. Each cell has ~30,000 proteins which do ~30,000 different functions.

8 Proteins Proteins are biomolecules which do everything in the cell. SEQUENCES Each cell has ~30,000 proteins which do ~30,000 different functions. Proteins are made up of different amino acids which are arranged in different orders (sequences). amino acids

9 Turn and Talk If proteins are made of amino acids, what is the monomer of a protein called? The monomer of a protein is called What is the polymer of a protein called? The polymer of a protein is called

10 Proteins SEQUENCES STRUCTURES Proteins are biomolecules which do everything in the cell. Each cell has ~30,000 proteins which do ~30,000 different functions. Proteins are made up of different amino acids which are arranged in different orders (sequences). Movement. Eyesight, digestion, structural support, enzymes, defense, transport. Proteins have different functions because they have different structures because they have different sequences of amino acids.
