atalysis definition or catalysis meaning can be given as the increase in the rate of a chemical reaction because of the participation of an additional substance, which is known as a catalyst. Catalyst is not consumed in the catalyzed reaction, but it can continue to act repeatedly. Even a small amount of catalyst is usually sufficient to bring about this effect. In contrast with the catalyzed mechanisms, usually, the catalyst reacts to generate a temporary intermediate, which then regenerates the original catalyst with the help of a cyclic process.
Reactant.
Substrates
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
In a catalyzed reaction, a reactant is often called a substrate because it is the specific molecule upon which the catalyst acts to increase the rate of the reaction without being consumed itself.
In enzyme-catalyzed reactions, the term "substrate" is synonymous with the molecule or molecules that the enzyme acts upon to produce a reaction. It is the specific substance upon which an enzyme acts to produce a product.

Substrates
The reactants of enzyme-catalyzed reactions are known as substrates. Substrates bind to the active site of an enzyme, where the reaction takes place. Enzymes help lower the activation energy required for the reaction to occur.
They are generally known as substrates.
Reactants. "Substrate" is another possibility.
Actually a substrate is a reactant. It undergoes a chemical reaction to yield a product. The difference is that a catalyst acts upon it to increment the rate of the reaction (by reducing the activation energy required).
The reaction will proceed until one of the reactants is fully consumed. Any excess of the other reactant will remain unreacted and be left over after the reaction is complete. The reactant that is in excess is known as the excess reactant.
