Hormones are the chemicals, which are released by a group of cells that are located at a specific location in the body. This specific location is known as glands. The hormones are signaling molecules that are transported through the circulatory system to the target sites. The hormones are secreted by the endocrine system. The hormones can be categorized as amine , peptide, steroid, and fatty acid derived molecules.

Summary Introduction

Introduction:

Hormones are the chemicals, which are released by a group of cells that are located at a specific location in the body. This specific location is known as glands. The hormones are signaling molecules that are transported through the circulatory system to the target sites. The hormones are secreted by the endocrine system. The hormones can be categorized as amine, peptide, steroid, and fatty acid derived molecules.

Expert Solution & Answer

Answer to Problem 1TYK

Correct answer:

Amines hormones are usually based on tyrosine.

Explanation of Solution

Justification for the correct answer:

Option (b) is based on tyrosine. This option is correct as these hormones are involved in the neuroendocrine signaling and classical endocrine signaling. All the amine hormones are derived from the amino acid tyrosine. Hence, option (b) is correct.

Justification for the incorrect answers:

Option (a) is hydrophilic, when secreted by the thyroid gland. This is false as thyroxine and triiodothyronine are not hydrophilic. Rest of them are hydrophilic. Thus, not all amine hormones are hydrophilic. So, it is an incorrect option.

Option (c) is paracrine but not autocrine. This is false as the amine hormones include epinephrine, norepinephrine, and dopamine. These hormones act as both paracrine and autocrine. So, it is an incorrect option.

Option (d) is not transported by the blood. This is false as they form a hydrophilic complex by binding to the hydrophilic carrier proteins and enter the blood-stream to reach their target. So, it is an incorrect option.

Option (e) is repelled by the plasma membrane. This is false as these hormones detach from the carrier protein as they come in contact with the plasma membrane. They pass through the plasma membrane to reach their nuclear receptor present in the target cell. So, it is an incorrect option.

Hence, options (a), (c), (d), and (e) are incorrect.

Conclusion

Therefore, it can be concluded that the amine hormones are derived from tyrosine amino acid. Most of the amine hormones are hydrophilic except thyroxine and triiodothyronine. They are transported by blood as they bind to hydrophilic carriers.
