The word enzyme mechanism is a scientific term used in biochemistry and molecular biology to describe the way in which enzymes work. Enzymes are biological molecules responsible for facilitating and regulating nearly all metabolic processes in living organisms.

Enzymes can be classified according to their function, structure, and ability to bind to substrate molecules. Enzymes are composed of amino acids, and their structure determines their function. Enzyme mechanism refers to the physical and chemical events that occur when an enzyme binds to its specific substrate molecule. It is these events that enable the enzyme to catalyze a reaction.

The enzyme mechanism begins when the enzyme binds to a substrate molecule. The enzyme molecules form an active site, which is a depression in the structure of the enzyme molecule in which the substrate molecule fits. This binding stabilizes the substrate molecule and allows the enzyme to interact with it. This interaction triggers a conformational change in the enzyme molecule that begins the catalytic reaction.

The conformational change in the enzyme causes it to act as a catalytic agent, speeding up the breakdown, change, or formation of the substrate molecule. This results in the formation of an enzyme-substrate complex, which is the intermediate state during which the enzyme is actively catalyzing the reaction.

Once the reaction is complete, the enzyme-substrate complex releases the product molecules and the enzyme is then free to bind to another substrate molecule and repeat the cycle. This is the enzyme mechanism, and it is a crucial part of metabolism and cellular processes in living organisms.
