Proteins are the workhorses of biological macromolecules. Some form enzymes that catalyze biochemical reactions, which are necessary for metabolism. Others give cells structure and support, such as proteins in the cytoskeleton. They also play vital roles in cell signaling, immune responses, the cell cycle, and many other biological activities. You can think of it this way: Anything that you can describe happening in a living organism, most likely proteins are either making it happen or regulating it.

Remember that proteins are assembled at the ribosomes. Transfer RNA (tRNA) transfers amino acids to the ribosomes. Each of the three forms of RNA plays a distinct role in the production of those very important proteins. Proteins control biochemical pathways within the cell. They direct the assembly of lipids, carbohydrates, and nucleotides. Proteins also direct cell structure and movement, and it's DNA and RNA that direct the making of proteins.
