Q1 · Beta-oxidation
NEET PGMediumExplanation
Carnitine shuttles long-chain fatty acids across the inner mitochondrial membrane via the carnitine palmitoyltransferase system. Carnitine deficiency impairs fatty-acid oxidation, causing muscle weakness and hypoglycaemia.
Q2 · Lipoproteins
NEET PGEasyExplanation
HDL carries out reverse cholesterol transport, moving cholesterol from peripheral tissues to the liver, and is protective against atherosclerosis. LDL delivers cholesterol to tissues and is atherogenic.
Q3 · Apolipoproteins
HardExplanation
Apo C-II activates lipoprotein lipase on capillary endothelium, releasing free fatty acids from triglyceride-rich lipoproteins. Apo A-I activates LCAT and Apo B-100 is the ligand for the LDL receptor.
Q4 · Ketone Bodies
MediumExplanation
Ketone bodies, namely acetoacetate, beta-hydroxybutyrate and acetone, are made in liver mitochondria from acetyl-CoA during fasting or diabetic ketoacidosis. Peripheral tissues, including the brain in prolonged fasting, use them for energy.
Q5 · Essential Fatty Acids
EasyExplanation
Linoleic acid, an omega-6, and alpha-linolenic acid, an omega-3, are essential because humans cannot synthesise them. They are precursors of arachidonic acid and other signalling molecules.
Q6 · Familial Hypercholesterolaemia
HardExplanation
Familial hypercholesterolaemia results from defective LDL receptors, impairing LDL clearance and causing very high LDL, tendon xanthomas and premature atherosclerosis. It is inherited in an autosomal dominant pattern.
Lipid Metabolism sits within Biochemistry, which carries the same syllabus in both exams. This set runs to 6 questions, each tagged Easy, Medium or Hard, 2 of them at Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Lipid Metabolism 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 Biochemistry examiners keep returning to.
FAQ
Yes. Every question and explanation in this Lipid Metabolism set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
Lipid Metabolism sits within Biochemistry, which appears in the same form in both syllabuses. Metabolism, enzymes and molecular biology, distilled to the pathways and deficiency states that repeat in previous year papers.
