Question 4 of 5
Steroid hormones function by binding to receptor proteins within the Once the hormone binds to a receptor, it activates
Correct Answer: B
Rationale: Steroid hormones (e.g., cortisol) bind nuclear receptors, entering the nucleus to activate gene transcription altering protein synthesis over hours. Nuclear second messengers aren't typical cAMP is membrane-based. Membrane binding fits peptides (e.g., insulin), not steroids, and genes aren't at membranes. Nuclear gene activation distinguishes steroid action, key to their genomic effects, unlike messenger or membrane errors.
Question 5 of 5
The hypothalamus secretes releasing and inhibiting hormones that regulate the production and secretion of hormones from the:
Correct Answer: B
Rationale: Hypothalamic releasing (e.g., TRH) and inhibiting (e.g., dopamine) hormones target the anterior pituitary, regulating hormones like TSH, ACTH master control. Adrenal cortex responds to ACTH, not directly hypothalamus. Posterior pituitary stores hypothalamic ADH/oxytocin, not regulated by releasing hormones. Thyroid follows TSH, not direct hypothalamic. Anterior pituitary's regulation distinguishes it, key to hypothalamic-pituitary axis, unlike downstream glands.
