Question

Chemically, hormones are
A) Carbohydrates
B) Proteins
C) Steroids
D) Both B and C

Answer 1

Hint:Hormones are chemical messengers that are released by the endocrine glands of the body directly into the blood and which controls the function of various parts of the body.

Complete answer:
Different hormones have different functions and they work on different parts of the body. Their functions can be growth and development, metabolism of food, sexual development and reproduction, cognitive function, maintaining body temperature. Some of the endocrine glands that release the hormones include pituitary gland, pineal gland, thymus, thyroid, adrenal glands, pancreas, testes and ovaries.

The hormones are divided into three classes which includes steroids, eicosanoids and some protein derivatives. The protein derivatives can be amines, proteins or peptides. These hormones released by the endocrine glands act on different sites. However, certain hormones can act on the same site as well where they are released. This is termed as autocrine signalling of the hormones.
Thus, hormones are made up of steroids or proteins.

Since hormones are formed of proteins and steroids, Option A, B & C are incorrect.
Option B and C both are correct choices on their own, so the correct answer is Option D.

Thus, the correct answer is option (D) Both B and C.

Note:If there is any abnormality in the release of hormones or even in the production of hormones, it can lead to diseases. Such diseases can be easily diagnosed in the laboratory by using the urine, blood or saliva samples.
