Differences in hormones, enzymes, neurotransmitters, and antibodies

Comparing projects Hormone Enzyme Neurotransmitter Antibody
Source Hormones are produced by certain cells in the body. Animal hormones are produced by the secretion of endocrine glands or endocrine-functioning cells Enzymes can be produced in all living cells (except for mammalian mature red blood cells and plant sieve cells) and can be distributed within and outside cells, and can also work outside the organism Can only be produced by nerve cells, released by the synaptic pre-membrane membrane Pulp cells are produced
The nature of chemistry There are many kinds of hormones, some are protein or peptides, such as thyroid-stimulating hormone, growth hormone, insulin, etc., and some are sterols, such as sex hormones. The vast majority of enzymes are proteins, and very few are RNA Acetylcholine, dopamine, norepinephrine, epinephrine, amino acids, nitric oxide, etc. Protein (immune globulin)
Place of action Specific target cells, target organs Catalysais of a specific chemical reaction within or outside the cell Receptors of the synaptic membrane The corresponding antigen
Condition of action Close lying to the nervous system Affected by pH, temperature and other factors    
Physiological function Hormones regulate and control the normal physiological activities of organisms Enzymes act as a catalyst for various chemical reactions in the body Transmission of nerve signals (signal molecules) between synapses, causing the membrane to excite or inhibit the synapse. Antibodies that bind to the corresponding antigens to form precipitation or cell groups are eventually swallowed by the cells and digested
