Question

what is the difference between enzyme and catalyst?​

Answer 1

Explanation:

Difference between enzyme and catalyst - definition

Enzymes are proteins that increase rate of chemical reactions converting substrate into product. Catalysts are substances that increase or decrease the rate of a chemical reaction but remain unchanged.

What is the difference between enzyme and catalyst?

Enzymes are organic biocatalysts, meaning that they are composed of and speed up reactions involving biological macromolecules. Catalysts are inorganic and can be either heterogeneous or homogeneous in composition. While both inorganic catalysts and organic biocatalysts act upon the same principle of reducing the activation energy of a reaction without being consumed in the reaction, biocatalysts (enzymes) are unique in that they are soluble proteins that can be specific to a particular reaction (i.e. they can bind to a very specific substrate via molecular recognition at the active site) and are specialized to catalyze very particular biochemical reactions (e.g. hydrolysis, phosphorylation, de-phosphorylation, uniquitin ligation, which again are dependent on the structure of the active site). Inorganic catalysts are not specific to any one specific reaction. Therefore, enzymes are a distinctly different class of catalysts.
