Key enzyme in glycogenolysis Debranching enzyme Glycogen phosphorylase Glycogen synthase Branching enzyme 5. a person with von Gierke’s disease has ketosis. All are true for ketosis in this patient except hypertriglyceridemia fat mobilisation is less hypoglycaemia Lactic acidosis 6. Amino acid which can be used in both gluconeogenesis and ketogenesis Valine Arginine Tyrosine Threonine 7. which of the following is seen in association with membrane raft mannose binding protein spectrin associated protein glycosylphosphatidylinositol anchored protein guanosine triphosphate associated protein 8. The protein rich in basic amino acids, which functions in the packaging of DNA in chromosomes, is Collagen hyaluronic acid binding protein Histone Fibrinogen 9. HMP shunt is of great importance in cellular metabolism because it produces NADPH Acetyl Co A ADP ATP 10. Glycogen synthase is activated by AMP Insulin Epinophrine Glucagon 11. Which vitamin is essential for metabolism of sulphur containing amino acids Vitamin C Thiamine Biotin Folic acid 12. Imidazole ring is present in Tryptophan Arginine Tyrosine Histidine 13. Urea is synthesized in all except Liver Brain Kidney Spleen 14. the structural proteins are involved in maintaining the shape of cell or in the formation of matrices in the body.the shape of these proteins is globular planar fibrous stretch of beads 15. In the fasting state glucose is obtained from None Liver glycogen Muscle glycogen Both 16. Which of the following is th metabolic pathway in which there is a shuttling of glucose and lactate between muscle and liver during physical exercise Hydrologic cycle Carbon cycle Glucose cycle Cori cycle 17. Most important source of ATP is- None of the above Substrate level phosphorylation Anaerobic glycolysis Oxidative phosphorylation 18. McArdles disease is due to deficiency of Glucose 1,6 diphosphatase Glucose 1 phosphatase Myophosphorylase Glucose 6 phosphatase 19. Which of the following is involved in both fatty acid catabolism and synthesis Co-enzyme A Carnitine malonyl Co enzyme A Alcohol dehydrogenase 20. all are involved in fast axonal transport except dynein lysosomes neurofilaments kinesin Loading … Question 1 of 20
