CHAPTER 5 (TRUE/FALSE) 2024- 2025
WITH COMPLETE QUESTIONS AND
ACCURATE SOLUTIONS GRADED A+
d1. The same chemical messenger may be either a hormone or a neurotransmitter, depending on its
source and mode of delivery to the target tissue. - Correct answer.T
2. A single endocrine gland may produce many hormones. - Correct answer.T
3. Neurohormones are hormones that specifically modify neural activity. - Correct answer.F
4. Specialization of target-cell receptors explains the specificity of hormonal
action. - Correct answer.T
5. The nervous system exerts considerable control over the endocrine system, but
hormones have no influence over the nervous system. - Correct answer.F
6. Peptide hormones are often produced as prohormones. - Correct answer.T
7. The hormones influence adjustments that require duration rather than speed,
whereas the rapid coordinations of the body are controlled by the nervous system. - Correct answer.T
8. All hormones are first formed as preprohormones then are pruned into active
hormones. - Correct answer.F
9. One target cell receptor may bind with more than one type of hormone. - Correct answer.T
, 10. Cholesterol is a common precursor for polypeptide hormones. - Correct answer.F
11. Endocrine responses occur more slowly and last longer than neural responses. - Correct answer.T
12. Minor differences in structure between hormones within each chemical
category often result in profound differences in biological response. - Correct answer.T
13. Tropic hormones target only other glands. - Correct answer.T
14. Metabolism of hormones always results in their inactivation. - Correct answer.F
15. Once a steroid hormone binds with its intracellular receptor, the hormonereceptor
complex binds with a specific hormone response element on DNA, thereby activating
a particular gene. - Correct answer.T
16. Peptide hormones cause changes in solute permeability or alter intracellular
protein activity at their targets. - Correct answer.T
17. Epinephrine produces diverse effects on the activity of smooth muscle. - Correct answer.T
18. A tropic hormone acts primarily on nonendocrine tissues. - Correct answer.F
19. Hormones may be steroids, peptides, or amines. - Correct answer.T
20. All hormones are synthesized by the endoplasmic reticulum-Golgi complex
system. - Correct answer.F
21. Insulin is produced as a prohormone. - Correct answer.F
