Difference Between Enzymes And Hormones

the enzymes are the biological catalysts that are used to speed up biochemical reactions. in this process, no chemical changes are undergone. on the other hand, hormones are peptoid or steroid molecules that are produced during organisms. they trigger a specific cellular reaction in specified and targeted tissues. the basic difference Between Enzymes And Hormones is that enzymes are secreted by ducts, travel through these ducts, their reaction is fast, and are involved in digestion while hormones are secreted by ductless glands, travel through the blood, are involved in metabolic activities, and are slow reactions.

Difference Between Enzymes And Hormones in Tabular Form

Enzymes Hormones
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.
Biological Catalyst Chemical Messengers
Macromolecules, always high molecule weight. Hormones have comparatively low molecular weight than enzymes.
No translocation Shows polar translocation
Enzymes react quickly Some hormones react quickly while some react slow.
Reversible. Irreversible.
Reaction increases with an increase in concentration. Deficiency or excess production leads to disease.
Predominantly composed of proteins Composed of proteins, amino acids, steroids, etc
Retains chemical make-up after use, hence can be reused Chemical composition changes after use, hence may or may not be reused
External factors acutely affect the regulation of enzymes such as temperature, pH levels, etc External factors do not affect hormones as acutely as enzymes.
Examples: Protease, amylase, and lipase are important enzymes for digestion, Oxidases, Hydrolases, Isomerase. Examples: Melatonin is the hormone that regulates your circadian rhythm (sleep cycle). Insulin is another hormone that regulates blood sugar. testosterone, Estrogen, Cortisol, Oxytocin.
