Difference Between Enzymes and Hormones

The human body is a complex piece of machinery that requires many biological functions to survive. Many chemicals that help the structure of the body and our body make certain vital functions of life possible. These “chemicals” can be divided into enzymes and hormones.

Difference Between Enzymes and Hormones

The main difference between enzymes and hormones is that enzymes act as catalysts for reactions, while hormones act as messengers that trigger various actions in the body.

Enzymes are a type of catalyst that helps the body carry out a reaction. This means that enzymes do not change the process or function but help increase the rate of a particular reaction. Enzymes such as sweat and saliva are produced in the external glands. Some other examples of enzymes are trypsin, amylase and maltase.

Hormones, on the other hand, are chemical messages that cause processes to occur. Hormones are diverse in composition, with some essentially consisting of steroids, amino acids, and also some protein structures. The pituitary and thyroid hormones are supplied by the endocrine glands.

Both plants and animals have hormones and enzymes, but secretion and purpose are different in both. The main feature that distinguishes hormones from enzymes is their chemical structure. Some other differences in Hormone vs. Hormone. Enzymes include the following.

Difference Between Enzymes and Hormones

Enzymes Hormones
Catalyst: Accelerates the rate of a reaction Messenger: Triggers functions in the body
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.
           Exocrine glands produce enzymes

(salivary glands, gastric glands)

Endocrine glands produce hormones

(thyroid and pituitary glands)

Enzyme secretion is not much affected by age Hormones secretion is affected by age (puberty)
Enzymes form and act at the site of production Hormones form and act at different sites
Examples: Protease, amylase, and lipase are important enzymes for digestion Examples: Melatonin is the hormone that regulates your circadian rhythm (sleep cycle)

Insulin is another hormone that regulates blood sugar

Hormones and enzymes play an important role in our body by controlling and regulating many functions. Hormones are known as chemical messengers because they cause many activities, while enzymes are catalysts because they affect the rate of reactions.
