Read Glucose Control and Its Failure
A focused NSEB read for the incretin regulation pattern. Learn the linked concept, then apply it in the source questions.
Incretin Regulation is the central idea in this question pattern. Identify the condition in the stem before applying the method below.
A gland sends a chemical message to a target
A gland sends a chemical message to a target
Identify the gland, its hormone and the effect separately. A deficiency or excess changes the normal response, not the gland’s location.
Incretin Regulation
Gut-brain-pancreas feedback changes after denervation. From the diagram, increased raises insulin sensitivity and is associated with reduced triglyceride/VLDL output. Therefore a agonist can reduce post-prandial hyperglycemia by improving insulin action (B) and can reduce VLDL in plasma (C). The antagonist statements do not follow from the diagram.
Trace the untreated diabetes cascade
Without insulin in Type I diabetes, blood glucose rises first. Once it exceeds the renal threshold, glucose enters urine; its osmotic effect causes polyuria, reducing blood volume and pressure until circulatory failure can follow. Keep the causal order: hyperglycemia → threshold exceeded → glucosuria → osmotic diuresis → volume/pressure fall → failure. Choose C.

- ✓Gut-brain-pancreas feedback changes after denervation
- ✓Hyperglycemia can cause glucosuria, osmotic diuresis and circulatory collapse in that order.
Read the conditions in the stem carefully and use the stated model, labels, or assumptions before choosing an answer.
