Difference between Enzymes and Hormones

The main difference between enzymes and hormones is that enzymes are biological catalysts that increase the speed of biochemical reactions without undergoing any changes themselves, whereas hormones are molecules produced by organisms that transmit messages to other organs or tissues, triggering specific cellular reactions.

Enzyme vs. Hormone

Here are the main difference between enzymes and hormones:

Character	Enzymes	Hormones
Definition	Enzymes are biological catalysts that increase the speed of biochemical reactions without any changes.	Hormones are molecules like steroids (testosterone/estrogen) or peptides (insulin) produced by a part of an organism and send messages to other organs or tissues for cellular reactions.
Chemical Name	Biological Catalyst	Chemical Messengers
Molecular Weight	Macromolecules, always high molecule weight.	Hormones have comparatively low molecular weight than enzymes.
Activity Performed	Performs at the place of origin, i.e., inside the cell.	Performs at some distance, i.e., target organ from glands.
Reutilization	Enzymes can be reused.	Hormones cannot be reused.
Formation	Formation is in exocrine glands.	Formation is in endocrine glands.
Specifications	It depends on functions performed by the substrate.	It depends on positive and negative feedback by target cells.
Circulatory System	Intracellular or some ducts.	Blood Stream.
Chemical Composition	Generally Proteins.	Polypeptides, Steroids, Amines.
Producer Cells	Salivary glands, cells in the stomach, pancreas, and glands in the small intestine.	Pituitary glands, Thyroid glands, Thymus glands, Adrenal glands, Pancreas.
Translocation	No translocation.	Shows polar translocation.
Reacting Time	Enzymes react quickly.	Some hormones react quickly while some react slowly.
Reaction Type	Reversible.	Irreversible.
Concentration	Reaction increases with an increase in concentration.	Hormone effects depend on the deficiency or excess of their concentration in the body.
