Chapter 45, Problem 1U

Which of the following best describes hormones?

a. Hormones are relatively unstable and work only in the area adjacent to the gland that produced them.

b. Hormones are long-lasting chemicals released from glands.

c. All hormones are lipid-soluble.

d. Hormones are chemical messengers that are released into the environment.

Expert Solution & Answer

Summary Introduction

Introduction:

Human body has four types of mechanisms for cell communication, which includes the endocrine signaling and direct contact. The communication within the cells controls various activities of the body.

Answer to Problem 1U

Correct answer:

Hormones are the long lasting chemicals secreted by the endocrine glands. Therefore, option b. is correct.

Explanation of Solution

Reason for the correct statement:

Hormones are the chemicals, which regulates several functions of the body. They are secreted in the extracellular fluid by the endocrine glands, and the blood carries them to the site of action. Hormones perform their action at a distance from where they were secreted.

Option b. is given as "Hormones are long-lasting chemicals released from glands".

As, “the hormones are secreted by the endocrine glands which remains in the blood for long, and they regulate the function of various parts of the body from a distance”, is the right answer.

Hence, option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “Hormones are relatively unstable and work only in the area adjacent to the gland that produced them”.

Hormones perform their action away from the site, from where they are secreted. They perform regulatory functions at a distance from their source. So, it is a wrong answer.

Option c. is given as “All hormones are lipid soluble”.

Certain types of hormones are lipid soluble and certain types of hormones are water soluble. So, it is a wrong answer.

Option d. is given as “Hormones are chemical messengers that are released into the environment.”

Hormones are released into the blood by the endocrine glands. So, it is a wrong answer.

Hence, options a., c., and d. are incorrect.

Conclusion

Hormones are the chemicals released from the glands, which remains for long in the circulatory system.
