SUMMARY
Enzymes are responsible for carrying out chemical reactions in living things. Enzymes act as catalysts that lower the activation energy of a chemical reaction by attaching to the substrate via induced fit.

Enzymes work in groups, forming metabolic pathways that produce specific cell products. To prevent waste of cell resources, metabolic pathways must be controlled. Because enzymes are responsible for carrying out the chemical reactions of metabolic pathways, if enzymes are inhibited, then the metabolic pathways are inhibited.

Both noncompetitive and competitive inhibitors affect enzymes. Noncompetitive inhibitors bind to allosteric sites on the enzymes. Competitive inhibitors compete with the substrate to bind to the enzyme's active site.
