Q1 · Insulin Action
NEET PGEasyExplanation
Insulin stimulates translocation of GLUT4 transporters to the cell membrane in skeletal muscle and adipose tissue, increasing glucose uptake. GLUT2 in liver and pancreas and GLUT1 for basal uptake are insulin-independent.
Q2 · Thyroid Hormone
NEET PGMediumExplanation
T3 is several times more potent than T4 at target tissues. Most circulating T3 is produced by peripheral deiodination of T4, which acts largely as a prohormone.
Q3 · Calcium Regulation
NEET PGMediumExplanation
PTH raises calcium by resorbing bone, increasing renal calcium reabsorption and activating vitamin D to boost gut absorption. It decreases rather than increases renal phosphate reabsorption, causing phosphaturia.
Q4 · Second Messengers
HardExplanation
Glucagon, along with ACTH, PTH and beta-adrenergic hormones, acts via Gs-protein-coupled receptors that raise cAMP. Insulin uses tyrosine kinase, while steroid and thyroid hormones use intracellular nuclear receptors.
Q5 · Adrenal Hormones
EasyExplanation
Aldosterone, from the zona glomerulosa, acts on the distal nephron to increase sodium reabsorption and potassium excretion, regulating extracellular volume and blood pressure. It is controlled by the renin-angiotensin system.
Endocrine sits within Physiology, which carries the same syllabus in both exams. This set runs to 5 questions, each tagged Easy, Medium or Hard, 1 of them at Hard, and 3 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Endocrine marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Physiology examiners keep returning to.
FAQ
Yes. Every question and explanation in this Endocrine set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
Endocrine sits within Physiology, which appears in the same form in both syllabuses. System-wise physiology with the mechanisms examiners test most: cardiac and respiratory regulation, renal handling, endocrine axes and nerve conduction.
