,1.0 Nutritional Biochemistry & Supplementation
1. Which of the following best describes the primary mechanism of
action of curcumin in neurodegenerative conditions?
A. Activation of acetylcholinesterase
B. Inhibition of phosphorylase kinase and reduction of COX-2 expression
C. Upregulation of tau phosphorylation
D. Stimulation of NF-kB pathways
Correct Answer: B
Rationale: Curcumin acts as an inhibitor of phosphorylase kinase, which
decreases tau phosphorylation. It also reduces COX-2 expression and
inhibits NF-kB, providing anti-inflammatory and neuroprotective effects.
2. A patient presents with a viral upper respiratory infection. Which
supplement is known to stimulate neutrophils and macrophages to kill
microorganisms, is nontoxic, and does not cause microbial resistance?
A. Echinacea
B. Goldenseal
C. Olive leaf extract
D. Vitamin C
Correct Answer: C
Rationale: Olive leaf extract stimulates neutrophils and macrophages to
kill microorganisms. It is nontoxic, does not cause microbial resistance,
and is useful for treating intracellular organisms.
3. Which of the following supplements functions primarily by
activating sirtuins and mimicking the effects of caloric restriction?
A. Resveratrol
B. CoQ10
,C. Alpha-lipoic acid
D. Melatonin
Correct Answer: A
Rationale: Resveratrol is a well-known sirtuin activator that mimics the
effects of caloric restriction, promoting longevity and cellular repair
mechanisms.
4. What is the primary mechanism by which berberine exerts its
hypoglycemic effects?
A. Increasing insulin secretion from pancreatic beta cells
B. Activating AMP-activated protein kinase (AMPK)
C. Inhibiting glucagon-like peptide-1 (GLP-1)
D. Blocking sodium-glucose cotransporters in the kidney
Correct Answer: B
Rationale: Berberine activates AMPK, which leads to increased glucose
uptake, improved insulin sensitivity, and inhibition of hepatic
gluconeogenesis.
5. Which form of vitamin D is considered the most biologically active?
A. Cholecalciferol (Vitamin D3)
B. Ergocalciferol (Vitamin D2)
C. 25-hydroxyvitamin D
D. 1,25-dihydroxyvitamin D
Correct Answer: D
Rationale: 1,25-dihydroxyvitamin D (calcitriol) is the biologically active
form of vitamin D, produced in the kidneys via hydroxylation of 25-
hydroxyvitamin D.
6. Which of the following is a primary mechanism of action for omega-
3 fatty acids (EPA/DHA) in reducing inflammation?
, A. Inhibiting cyclooxygenase-2 (COX-2) directly
B. Blocking histamine receptors
C. Displacing arachidonic acid in cell membranes and reducing
eicosanoid production
D. Activating the NLRP3 inflammasome
Correct Answer: C
Rationale: Omega-3 fatty acids compete with arachidonic acid for
incorporation into cell membranes, thereby reducing the production of
pro-inflammatory eicosanoids and cytokines.
7. A patient with cardiovascular disease is prescribed CoQ10. What is
the primary rationale for this supplementation?
A. It acts as a vital electron carrier in the mitochondrial electron
transport chain and has antioxidant properties
B. It directly lowers LDL cholesterol
C. It increases nitric oxide production
D. It blocks calcium channels in vascular smooth muscle
Correct Answer: A
Rationale: CoQ10 is essential for ATP production in the mitochondria
and acts as a lipid-soluble antioxidant, protecting cell membranes from
oxidative damage.
8. Which mineral is a critical cofactor for over 300 enzymatic reactions,
including those involving ATP production and insulin signaling?
A. Calcium
B. Iron
C. Zinc
D. Magnesium
Correct Answer: D
Rationale: Magnesium is a cofactor for over 300 enzymes, playing a
