Enzymes
... A key portion of the enzyme is the active site (E 1). The active site is the region in which reactants bind and, essentially, the region where the chemical reaction takes place. We will now describe one way that enzymes operate-enzymes can operate in several different ways to speed reactions. In thi ...
