The main difference between hormone and enzyme is that hormone is the substance that is produced by the body and transported to tissue fluids causing stimulation of specific cells or tissues, while enzyme is the substance produced by the living body that acts as catalyst. to provoke biochemical reactions.

Hormone vs enzyme

A hormone is a regulatory substance; on the other hand, the enzyme is the catalytic substance. The hormone produced by organisms and transported to target cells, causing stimulation of specific cells and tissues; on the other hand, the enzyme is also produced by the living organism and acts as a catalyst to cause various biochemical reactions. The hormone has a low molecular weight; on the opposite side, an enzyme has a comparatively high molecular weight.

The hormone easily passes through the lipid cell membrane; On the other side of the coin, the enzyme cannot cross the lipid cell membrane. The hormone acts as signals that pass between cells or organs; On the other side of the coin, the enzyme can only catalyze chemical reactions by increasing the metabolic rate. Regulated hormone factors are brain and external factors; on the other hand, the regulated factors of the enzyme are isoenzymes, covalent modification, protein turnover, proteolytic activation.

Each hormone has a wide variety of functions such as reproduction, growth and development; on the other hand, the enzyme has a unique and specific but specific function. The hormone acts far from the site of production; on the other hand, the enzyme acts at the synthesis site.

The functions of the hormone depend on negative and positive feedback; on the other hand, the functions of the enzyme in the presence and absence of substrate. The increase or decrease of the hormone causes some pathological changes in the body; the insufficiency of the hormone causes diseases.

What is the hormone?

A hormone is a regulatory substance that is produced by living organisms and transported by the blood away from the secretion site and acts on different target cells, such as cells, organs and tissues. The hormone can be secreted from both types of glands which are endocrine and exocrine. The main regulatory factors that regulate the production of hormones are mainly the brain and other external factors.

The functions of the hormone can have a variety of diversity, such as reproduction, growth and development. The functions of the hormone depend on the positive and negative feedback systems. Its effectiveness changes with the age of the human being. The molecular weight of the hormone is very low and it is comparable to other substances in the body.

What is an enzyme?

The enzyme is the catalytic substance that living organisms produce. It acts where they are secreted or away from the synthesis site. It causes the catalysis of many biochemical reactions. Only the exocrine gland system secretes enzymes. The main regulatory factors for enzyme production are isoenzymes, covalent modification, proteolytic activation, and protein turnover.

The functions of enzymes are unique and specific causing an increase in the speed of specific biochemical reactions by a specific enzyme. Its function depends mainly on the amount of substrate in the cells. Its effectiveness does not change with the age of the human body. The molecular weight of the enzyme is very high compared to other substances in the body.

Enzyme functions are affected by high temperature, heat, and pH. Enzymes cause the breakdown of large molecules into smaller molecules or the binding of small molecules into large molecules. Enzymes are insoluble in lipids, so they cannot cross the lipid cell membrane. That is why each enzyme is produced within the cell nucleus and cytoplasm and is used within the cell. Examples of enzymes are hydrolases, oxidases, isomerases, peroxidases and catalases, etc.

1. The hormone produced by the body and that acts on different tissues and cells as a regulatory substance; on the other hand, the enzyme is produced by the body and acts on different substrates.
2. The function of the hormone depends on the negative and positive feedback systems, while the function of the enzyme depends on the amount of substrate in the cell.
3. The increase or decrease in hormonal levels causes pathological diseases; on the other hand, insufficient enzymes mainly cause disease.
4. The effectiveness of the hormone changes with age, while the effectiveness of the enzyme remains the same and does not change with age.
5. The hormone is produced by both the endocrine and exocrine glands, on the other hand, the enzyme is produced by the exocrine glands.
6. The hormone has a low molecular weight; on the other hand, the enzyme has a comparatively high molecular weight.
7. The hormone is the regulatory substance, while the enzyme is the catalytic substance.
8. A hormone is not affected by high temperature and pH; on the opposite side, the enzyme is affected by high temperature and pH.
9. The hormone has various functions; on the other hand, the enzyme has a unique and specific function.
10. The regulatory factors of the hormone are brain and external factors; on the other hand, the regulatory factors of the enzyme are isoenzymes, covalent modification, protein turnover and allosteric control.

Final Thought

The above discussion concludes that the hormone is produced by the endocrine and exocrine glands, while the exocrine glands produce the enzyme.
