Introduction

Enzymes are biological catalysts that aid in the speeding up of chemical reactions in living organisms. Proteins called enzymes bind to substrates, alter them, and then produce a product.

The substrate binds to the active site of an enzyme, which subsequently produces a product through an enzymatic process. Enzyme kinetics is the study of an enzyme's reaction rate and the factors that govern it.

Allosteric regulation occurs when a regulatory molecule, such as an activator or inhibitor, binds to an enzyme's allosteric site (which is different from the active site). The binding of a regulatory molecule causes an enzyme's conformation to change.
