Small organic molecules that are either weakly bound (cosubstrates) or tightly bound (Prosthetic groups) to the enzyme. Irreversible inhibitors are generally specific to one group of enzymes as they destroy the enzymes by altering the active site and not by destroying the structure of the proteins. Similar to puzzle pieces fitting together, the active site can only bind certain substrates. An active site is normally HYDROPHOBIC in nature, not hydrophilic. they may need a cofactor to be functional a protein binds is called a substrate is region Site of an enzyme and opens the active site found deep inside the enzyme they may need a to.

What is the active site of an enzyme simple definition? ; induced fit: Proposes that the initial interaction between enzyme and substrate is relatively weak, but that these weak interactions rapidly induce conformational changes in the enzyme that strengthen binding. The active site is specific for the reactants of the biochemical reaction the enzyme catalyzes. The enzyme-substrate complex can also lower activation energy by bending substrate molecules in a way that facilitates bond-breaking, helping to reach the transition state. The active site refers to the specific region of an enzyme where a substrate binds and catalysis takes place or where chemical reaction occurs. The weight is then removed and the ice is melted by putting it in contact with a high-temperature reservoir at 1C.1^{\circ} \mathrm{C}.1C.
