Ans.?1
18. The main enzyme responsible for activation of xenobiotics is:
1.Cytochrome P-450
2.Glutathione S-transferase.
3.NADPH cytochrome P-450-reductase.
4.Glucuronyl transferase.
Ans. three [ Harper ed 23rd page 705 Chapter 61-Xenobiotics Mentions that NADPH cytochrome P-450-reductase is involved NOT NADH]

1.An abnormality in porphyrin part of hemoglobin.
2.Replacement of glutamate by valine in B-chain of HbA.
3.A nonsense mutation in the B-chain of HbA.
4.Substitution of valine by glutamate in the a-chain of Hba.
Ans. 2

1.Urogenital sinus.
2.Hypertrophied clitoris.
3.Miocropenis.
4.Vulval hematoma.
Ans. two
21. reduced Glycolytic activity impairs oxygen transport by hemoglobin due to:
1.Reduced energy production.
2.Decreased production of 2,3-bisphosphoglycerate.
3.Reduced synthesis of hemoglobin.
4.Low levels of oxygen.
Ans. 2

23. The conversion of an optically pure isomer (enantiomer) into a mixture of equal amounts of both dextro and levo forms is called as:
1.Polymerization.
2.Stereoisomerization.
3.Racemization.
4.Fractionation.
Ans. 3
24. The protein rich inbasic amino acids, which functions in the packaging of DNA in chromosomes, is:
1.Histone.
2.Collagen.
3.Hyaluronic acid binding protein.
4.
Ans.1
25. A 56 year old man presents in the casualty with severe chest pain and difficulty in breathing. His ECG was taken immediately.\
The above ECG suggest the subsequent diagnosis:
1.Ventricular fibrillation.
2.Acute pulmonary embolism.
3.Second degree heart block.
4.Atrial fibrillation.
Ans. ? [ Here ECG appears insignificant, as history is suggestive of PE] [other view - Varying R - R interval which can only be in 3/4 choice]
