Endocrine System
Section 1: Hormone Classification & Mechanisms (Questions 1-20)
1. Which of the following is a steroid hormone?
A) Epinephrine
B) Cortisol
C) Thyroid-stimulating hormone (TSH)
D) Insulin
Cortisol is derived from cholesterol and is a steroid hormone. Epinephrine, TSH, and insulin
are peptides/protein hormones.
2. A hormone that is lipid-soluble will:
A) Bind to membrane receptors
B) Activate second messengers (e.g., cAMP)
C) Diffuse through the plasma membrane and bind to intracellular receptors
D) Be stored in large vesicles before release
Lipid-soluble hormones (steroids, thyroid hormones) cross the plasma membrane freely
and bind to intracellular or nuclear receptors to alter gene transcription. Water-soluble
hormones bind to membrane receptors.
3. Which second messenger is commonly activated by water-soluble hormones?
A) cAMP
B) DNA
C) Calcium stored in the nucleus
D) ATP
, Water-soluble hormones bind to membrane G-protein coupled receptors and often use
cyclic AMP (cAMP) or IP3/DAG as second messengers to trigger intracellular responses.
4. Peptide hormones are typically:
A) Synthesized on demand from cholesterol
B) Stored in secretory vesicles until released
C) Carried in the blood bound to transport proteins
D) Able to directly enter the nucleus
Peptide hormones are synthesized as preprohormones, processed, and stored in secretory
vesicles; they are released by exocytosis and circulate freely (not bound to carriers).
5. Which of the following is an example of a paracrine signal?
A) Thyroid hormone acting on heart cells
B) Estrogen acting on uterine cells
C) Somatostatin from pancreatic delta cells inhibiting nearby alpha cells
D) Growth hormone acting on liver cells
Paracrine signals act locally on nearby cells. Somatostatin from delta cells acts on adjacent
alpha cells in the pancreas. Hormones like thyroid hormone or estrogen act at distant target
tissues (endocrine signaling).
6. What is the primary function of plasma albumin?
A) Blood clotting
B) Maintaining colloid osmotic pressure
C) Antibody production
D) Transporting lipids
Albumin is the most abundant plasma protein and is primarily responsible for maintaining
colloid osmotic (oncotic) pressure, which regulates fluid balance between blood and tissues.
7. Which of the following is an example of an eicosanoid hormone?
