Enzymes

Enzymes are regulatory proteins that assist in many of the reactions and processes in living cells. The DNA of a cell contains the master plan for the creation of the enzymes that are needed for life processes, and the enzymes assist in the replication of DNA and in fact help with making other copies of themselves and other proteins. One perspective on enzymes is that they facilitate many chemical reactions that otherwise would be too slow to sustain living systems. They may have binding sites which hold two or more other molecules to facilitate their binding to one another and also a binding site for ATP to provide the energy necessary for accomplishing the bonding.

Enzymes frequently require helper molecules called coenzymes to facilitate their work.
