1. Maple syrup urine disease is due to Mutase isomerise alpha-ketoacid decarboxylase Transaminase 2. most non polar amino acid is leucine glycine arginine lysine 3. cell differentiation by surface markers G banding Flow cytometry Spectrometry Electrophoresis 4. Cori’s cycle is concerned with transport of Lactate Glutamate None Alanine 5. Folding of protein chain is due to Hydrogen bonds Amide bond phosphodiesterase bonds Disulphide bond 6. Which of the following transports lactate from muscle to liver Glutamate Alanine Gutamine Aspartate 7. NAD+ acts as a conenzyme for Succinate dehydrogenase Malate dehydrogenase Xanthine oxidase L-amino acid oxidase 8. Which of these is most effective for gluconeogenesis Acetyl-CoA stimulation of pyruvate carboxylase Fructose -2,6 biphosphate stimulation of phophofructokinase-2 Fructose-1,6 biphosphate stimulation of phophofructokinase-1 Citrate stimulation of acetyl carboxylase 9. Phenyl ketonuria is caused by defective metabolism of carbohydrates fats nucleic acids amino acids 10. CO acts by inhibiting which component of respiratory chain- NADH CoQ reductase Cytochrome b Oxidative phosphorylation Cytochrome C oxidase 11. Which of the following is involved in both fatty acid catabolism and synthesis Carnitine Alcohol dehydrogenase Co-enzyme A malonyl Co enzyme A 12. nephrometry is based on the principle of refraction of light light attenuated in intensity by scattering filtration of solutes by kidney reduced transmission of light 13. Regulating enzymes in gluconeogenesis are all ,except Glucose -6 phosphatase PFK-1 Pyruvate Carboxylase PEP carboxykinase 14. action of a-sununit of G protein is breakdown of GTP to GDP intemalization of receptors binding of agonists conversion of GDP to GTP 15. “Classical phenyl ketonuria” is caused by deficiency of Phenylalanine hydroxylase Phenylalanine transaminase Tyrosine transaminase Tyrosine hydroxylase 16. All are true regarding glucose 6 phosphate deficicency except Hyperglycemia Increased mobilisation of glycogen from liver Hyperuricemia Defective cori cycle 17. Glycogen breakdown leads to formation of glucose and lactic acid glycoprotein lactic acid glucose 18. Creatinine is formed from Glycine Lysine Leucine Histamine 19. Histidine is the most important amino acid for buffering in normal conditions because It regulates kidney acid-base balance Pka value is very low Pka value is higher than pH Pka value is closer to pH 20. which receptors are present in liver for uptake of LDL Apo E and Apo B 100 Apo E Apo A and Apo E Apo B 100 Loading … Question 1 of 20
