Q-4 Clinical Case with 5 questions 10 marks
Recently , a town in India witnessed death of many children in span of few
days. On investigation, it was found that parents of most such children were
working as laborers in Litchi farms. Children ate lar ge amount of unripe
litchi fallen on ground, hypoglycin A (Amino-methylenecyclopropyl
propanoic acid) present in litchi was responsible for the event.
Hypoglycin A is metabol ised by body to methyle necyclopropyl acetyl-
Co-A (MCP A-Co-A) and MCP A-carnitine. The metabolites inhibit
fatty acid transport into mitochondria and its metabolism by Acyl-Co-A
dehydrogenase. Inhibitio n of beta-oxidation leads to excess utilization
of glucose in fasting state, leading to hypoglycemia. Hypoglycemic
encephelopathy leads to death.
Q.l How fatty acids are transported in to mitochondria?
Q.2 Explain reaction catalysed by Acyl-Co-A dehydrogenase.
Q.3 Action potential transmission requires ener gy . Explain.
Q.4 Hypoglycemia is more dangerous to brain as compared to other or gans.
Explain
Q.5 Draw flow-chart explaining biochemical basis ef fects of Hypoglycin A
on body .
Q-5 Answer in few lines(5 out of 7) 10 marks
a) Premature baby tends to develop respiratory distress syndrome
b) Hyperuricemia may be observed in von Gierke,s disease.
c) Odd chain fatty acids are glucogenic.
d) Hyperventilation aggravate tetany .
e) Pregnant woman frequently suf fers from anemia
f) Saturated fatty acids decrease fluidity of membrane.
g) Glucose helps Na+ absorption
Q-6 Answer in one or two lines (5 out of 6) 05 marks
a) Keratan sulfate & Hyaluronic acid
b) Biochemical changes in starvation
c) List metabolic pathways operating in mitochondria
d) T otal parenteral nutrition
e) Diabetes mellitus and diabetes insipidus
f) Diagnostic criteria for diabetes mellitus
