Hope this helps ;)

The main classification of chemical bonds are covalent, ionic, and metallic bonds.

The chemical bonds are the bridge like structure which is formed when one element reacts with other element and leads to the formation of new compound.

The following are the main types of bonds:

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
