These are the chemicals that speed up chemical reactions.
but all catalysts aren't enzymes...
Enzymes are catalysts.
Enzymes are catalysts.
There are mainly two types of catalysts: homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase. Homogeneous catalysts are usually dissolved in the same solvent as the reactants, while heterogeneous catalysts are typically solid catalysts in contact with the reactants.
enzymes are biological catalysts

Catalysts
Of course not, catalysts doesn't react.
Enzymes are natural catalysts, these natural catalysts speed up reactions.
Without catalysts many chemical reactions cannot occur; biological catalysts are called enzymes.
catalysts speed up a reaction
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
