Questions and Correct Updated Answers
(2025-2026) Set.
List 3 Types of Hormones: - Answer 1. Amino Acid Derivatives
2. Peptide Hormones
3. Steroid Hormones ( Lipid Derivatives)
Chemical messengers that are released in one tissue on transported in the bloodstream to alter
the activities of specific cells in other tissues - Answer Hormones
Specific cells that have the receptors needed to bind and "read" hormonal message when it
arrives - Answer Target Cells
Derived from cholesterol; Released by the reproductive organs (androgen by testes in males,
estrogen and progesterone by ovaries in females) by cortex of adrenal glands (corticosteroids)
and by the kidneys (calcitrol). Bound to specific transport proteins in plasma and remain in
circulation longer - Answer Steroid Hormones
Chains of amino acids; synthesized as prohormones--inactive molecules that are converted to
active hormones before or after they are secreted - Answer Peptide Hormones
Small molecules that are structurally related to amino acids, building blocks of proteins - Answer
Amino Acid Derivatives
List Amino Acid Hormones: - Answer Derivatives of Tyrosine:
~ Thyroid hormones
~ Catecholamines: Epinephrine, norepinephrine, dopamin
Derivatives of Tryptophan:
~ serotonin, melatonin
List Peptide Hormones: - Answer Glycoproteins
~ Thyroid-stimulating hormone (TSH)
, ~ oxytocin (OXT)
Small proteins
~ Growth hormone (GH)
~ prolactin (PRL)
List Steroid Hormones: - Answer ~ Reproductive organs: androgens by the testes in males&
estrogens and progestins by the ovaries in females
~ Cortex of the adrenal glands: corticosteroids
~ Kidneys: calcitriol
The Pituitary Gland releases nine important peptide hormones: - Answer Anterior Lobe:
~ ACTH
~ TSH
~ GH
~ PRL
~ FSH
~ LH
~ MSH
Posterior Lobe:
~ Oxytocin
~ ADH
TSH:
- Target:
- Effect:
- Released to: - Answer Thyroid-stimulating Hormone
- Target: thyroid gland
- Effect: secretion of thyroid hormones
- Released to: Thyrotropin-releasing hormone (TRH)
ACTH:
