(Created page with "== Enzyme Inhibitor == An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. Since enzymes catalyze nearly all of the chemical reactions in biological systems, enzyme inhibitors are a crucial area of study in biochemistry and pharmacology. They are used in medicine to treat various diseases, in agriculture to control pests, and in research to study enzyme function and metabolic pathways. == Types of Enzyme Inhibitors == Enzyme inhibitor...") |

Competitive inhibitors bind to the active site of the enzyme, competing directly with the substrate. This type of inhibition can be overcome by increasing the concentration of the substrate. An example of a competitive inhibitor is methotrexate, which inhibits the enzyme dihydrofolate reductase. | Competitive inhibitors bind to the active site of the enzyme, competing directly with the substrate.
