What are the different types of enzymes
... What are Enzymes? Enzymes are substances that function as organic catalysts, in other words, they either start chemical reactions or make them run faster. They accomplish this while remaining unchanged themselves. Enzymes are composed of two parts, a protein portion called the apoenzyme and a nonpro ...
