Question

What is a hormone?
A. Glandular secretion
B. Enzyme
C. Chemical messenger
D. Organic complex substance

Answer 1

Hint: The hormones are the chemical substances that are released by the endocrine glands of our body which are ductless glands. The hormones are the low molecular weight chemicals. They are conducted by the blood.

Complete answer:
Hormones are the chemical messengers that are made up of either proteins or amines, peptides, steroids, catecholamines, fatty acids, and glycoproteins. The hormones have the following characteristics –
1. Hormones are water-soluble.
2. They usually work away from their origin.
3. They are never stored.
4. They are anti-allergic.
5. They are not associated with antibody formation.
6. They are anti-inflammatory.
7. They are required for metabolism.
8. They are destroyed after their action.
9. The hormones are secreted from the Endocrine glands. A gland is a group of cells that does secretions. 10. The endocrine glands are the ductless glands. As they do not possess ducts so their secretions are directly poured into the blood.
So, option C is the correct answer.

Note: Hormones are secreted by endocrine glands because they are ductless so they are directly released into the bloodstream. There are different types of hormones based on nature some are proteinous, peptide, amino-acid derivatives, etc. Some of the hormones work just opposite to each other, however, some hormones work together and have the same function.
