Proteins are abundant in all organisms and are indeed fundamental to life.
Enzymes are involved in the reading of genetic information stored in DNA, the first step in the synthesis of proteins themselves. In addition, the non-protein components of cells are synthesized by enzymes. The rates of the reactions they catalyze are generally increased by the order of at least a million-fold. In fact, some RNA molecules, called 'ribozymes' have been shown to have catalytic activity, so that in fact not all enzymes are proteins. Transport Proteins are involved in the transportation of particles ranging from electrons to macromolecules.
