    • A) Thyroid-stimulating hormone (TSH)
    • B) Luteinizing hormone (LH)
    • C) Adrenocorticotropic hormone (ACTH)
    • D) Growth hormone (GH)
  2. 2.

    Which of the following hormones is synthesized by neurons in the hypothalamus and stored in the posterior pituitary gland prior to secretion?

    • A) Oxytocin
    • B) Thyroid-stimulating hormone
    • C) Adrenocorticotropic hormone
    • D) Growth hormone
  3. 3.

    Which of the following pairs of hormones exerts antagonistic effects to maintain calcium ion homeostasis in human blood plasma?

    • A) Epinephrine and norepinephrine
    • B) Insulin and glucagon
    • C) Aldosterone and cortisol
    • D) Calcitonin and parathyroid hormone
  4. 4.

    Which of the following statements correctly describes the primary mechanism by which water-soluble peptide hormones trigger a response in their target cells?

    • A) They bind to specific receptors located on the plasma membrane, activating intracellular second-messenger pathways.
    • B) They diffuse freely through the lipid bilayer to directly bind hormone response elements within the nucleus.
    • C) They cross into the cytosol to function as active coenzymes within mitochondrial metabolic pathways.
    • D) They are transported into the nucleus where they directly alter chromatin structure without receptor involvement.
  5. 5.

    Which of the following statements correctly describes a general characteristic of lipid-soluble (steroid) hormones?

    • A) They bind primarily to cell-surface receptors to trigger rapid second messenger cascades.
    • B) They cross the plasma membrane to bind intracellular receptors that regulate gene transcription.
    • C) They circulate freely dissolved in the blood plasma without the aid of transport proteins.
    • D) They are pre-synthesized and stored in large quantities within membrane-bound secretory vesicles.
