Multiple Choice Questions Endocrine System Questions
Question 1 of 5
Regarding insulin
Correct Answer: B
Rationale: Somatostatin inhibits insulin secretion from β-cells, reducing glucose uptake regulatory role. Insulin promotes protein synthesis, not catabolism anabolic. Phenytoin doesn't notably stimulate insulin glucose metabolism does. Insulin increases K⺠uptake with glucose, not decreases. Somatostatin's inhibition distinguishes it, key to pancreatic regulation, unlike anabolic, drug, or K⺠errors.
Question 2 of 5
Which of the following statements does NOT describe a step in the synthesis and secretion of T3 and T4?
Correct Answer: D
Rationale: T3 and T4 synthesis involves iodide trapping, oxidation to iodine, tyrosine iodination, and coupling not calcitonin synthesis, which occurs in separate thyroid C-cells for calcium regulation. This exclusion distinguishes thyroid hormone production, essential for metabolism, from unrelated calcitonin processes.
