,Q1 ANALYZE THE RELATIONSHIP BETWEEN STRUCTURE AND FUNCTION AT THE
CELLULAR, TISSUE, AND ORGAN LEVELS
In a cell that is actively synthesizing steroid hormones, which organelle would be
most abundant, and what is the primary mechanism by which these hormones are
released?
A. Rough endoplasmic reticulum; exocytosis of secretory vesicles
B. Smooth endoplasmic reticulum; diffusion across the plasma membrane CORRECT
C. Golgi apparatus; exocytosis of secretory vesicles
D. Free ribosomes; diffusion across the plasma membrane
RATIONALE: Steroid hormones are lipid-soluble and synthesized by enzymes in the smooth ER.
They diffuse directly through the plasma membrane without the need for vesicular transport.
Rough ER and Golgi are involved in protein synthesis and processing, not lipid synthesis. Free
ribosomes synthesize cytoplasmic proteins, not hormones.
Q2 ANALYZE THE RELATIONSHIP BETWEEN STRUCTURE AND FUNCTION AT THE
CELLULAR, TISSUE, AND ORGAN LEVELS
During the healing of a deep skin wound, which sequence of events correctly
describes the transition from the proliferative phase to the remodeling phase?
A. Fibroblasts lay down collagen; granulation tissue forms; collagen is reorganized and
cross-linked CORRECT
B. Inflammatory cells infiltrate; macrophages clear debris; scar tissue is formed immediately
C. Keratinocytes migrate; blood clot forms; collagen is degraded permanently
D. Angiogenesis occurs; myofibroblasts contract; elastin replaces all collagen
RATIONALE: In the proliferative phase, granulation tissue (containing fibroblasts and new
capillaries) forms, and fibroblasts produce collagen. In the remodeling phase, collagen is
reorganized and cross-linked to increase tensile strength. Option B is incorrect because scar
tissue is not formed immediately; inflammation precedes proliferation. Option C is incorrect
because the blood clot forms before keratinocyte migration, and collagen is not permanently
degraded. Option D is incorrect because elastin does not replace collagen.

,Q3 ANALYZE THE RELATIONSHIP BETWEEN STRUCTURE AND FUNCTION AT THE
CELLULAR, TISSUE, AND ORGAN LEVELS
Which of the following best explains why a patient with a complete transection of
the spinal cord at T1 would still have a withdrawal reflex in the lower limb?
A. The reflex arc is processed entirely in the brain, which remains intact
B. The reflex arc is mediated by the spinal cord, independent of higher brain centers
CORRECT
C. The reflex arc is mediated by the sympathetic chain ganglia
D. The reflex arc is mediated by the peripheral nerve plexus without spinal cord involvement
RATIONALE: A withdrawal reflex is a spinal reflex that involves a reflex arc entirely within the
spinal cord, without requiring input from the brain. Even with a complete spinal cord transection,
the reflex can still occur because the arc is intact below the level of injury. Option A is incorrect
because the brain is not required. Option C is incorrect because sympathetic ganglia are not part
of the somatic reflex arc. Option D is incorrect because the reflex requires the spinal cord.
Q4 ANALYZE THE RELATIONSHIP BETWEEN STRUCTURE AND FUNCTION AT THE
CELLULAR, TISSUE, AND ORGAN LEVELS
A researcher is studying a newly discovered hormone that increases the number
of aquaporins in the collecting duct of the kidney. Based on its mechanism, this
hormone most likely acts via which intracellular signaling pathway?
A. Direct gene activation by binding to an intracellular receptor
B. Activation of adenylyl cyclase and production of cAMP CORRECT
C. Activation of phospholipase C and production of IP3
D. Activation of receptor tyrosine kinase and MAP kinase cascade
RATIONALE: Aquaporin insertion into the collecting duct membrane is mediated by vasopressin
(ADH), which acts via the cAMP second messenger system. Binding to a G-protein coupled
receptor activates adenylyl cyclase, increasing cAMP and activating protein kinase A, which
triggers aquaporin-containing vesicle fusion. Intracellular receptors mediate lipid-soluble
hormones, not rapid aquaporin insertion. IP3 and tyrosine kinase pathways do not directly
regulate aquaporin trafficking.

, Q5 ANALYZE THE RELATIONSHIP BETWEEN STRUCTURE AND FUNCTION AT THE
CELLULAR, TISSUE, AND ORGAN LEVELS
Which of the following best explains why the risk of bone fracture increases
significantly in postmenopausal women, and what is the primary cellular
mechanism?
A. Decreased estrogen leads to increased osteoclast activity, causing net bone resorption
CORRECT
B. Decreased estrogen leads to increased osteoblast activity, causing bone overgrowth
C. Decreased calcitonin leads to decreased osteoclast activity, causing brittle bones
D. Decreased parathyroid hormone leads to decreased calcium absorption, causing
osteomalacia
RATIONALE: Estrogen inhibits osteoclast activity. After menopause, estrogen levels drop, leading
to increased osteoclast activity and net bone resorption, which increases fracture risk. Osteoblast
activity does not increase; it may decrease. Calcitonin has a minor role, and PTH is not
decreased; it often increases with age. Osteomalacia is due to vitamin D deficiency, not estrogen
loss.
Q6 ANALYZE THE RELATIONSHIP BETWEEN STRUCTURE AND FUNCTION AT THE
CELLULAR, TISSUE, AND ORGAN LEVELS
In a patient with myasthenia gravis, autoantibodies destroy acetylcholine
receptors at the neuromuscular junction. Which of the following would be an
expected immediate physiological consequence?
A. Increased muscle contraction due to more acetylcholine in the synaptic cleft
B. Decreased muscle contraction due to reduced end-plate potential generation CORRECT
C. Increased muscle contraction due to upregulation of acetylcholinesterase
D. No change in muscle contraction because acetylcholine can still bind to voltage-gated sodium
channels
RATIONALE: In myasthenia gravis, fewer ACh receptors mean that the end-plate potential is
smaller and may not reach threshold, so muscle contraction is weakened. Acetylcholine levels
are normal, but receptors are reduced. Upregulation of acetylcholinesterase would worsen
transmission. ACh does not bind to sodium channels; it binds to ligand-gated channels.
