What is the Origin of Competitive Inhibition?

This fundamental concept is derived from the principles of enzyme kinetics, a field formalized in the early 20th century to mathematically describe the rates of biochemical reactions. The term highlights the competition between two similar molecules for a single, limited biological binding site.

What is the Mechanism of Competitive Inhibition?

The key feature of competitive inhibition is that the inhibitory effect can be overcome by significantly increasing the concentration of the natural substrate, which then outcompetes the inhibitor for the active site. This reversible binding is a cornerstone of rational drug design, utilized by many pharmaceutical agents, such as aromatase inhibitors that compete with androgens for the aromatase enzyme.

Competitive Inhibition

Meaning

Competitive inhibition is a specific type of enzyme or receptor regulation where an inhibitory molecule structurally mimics the natural substrate or ligand, binding reversibly to the active site. By occupying this binding pocket, the inhibitor prevents the native molecule from initiating the physiological reaction or signal transduction cascade. This mechanism effectively reduces the apparent affinity of the enzyme or receptor for its true substrate.
