1. Mitochondrial membrane protein contain transporter of- NADPH ATP Acetyl COA NADH 2. A cell membrane is damaged by insertion of a microneedle. Repair of the membrane occurs by requires enzymatic action an active process requiring hydrolysis of ATP Hydrophobic interactions Protein interactions 3. The molecule, which is the initiator of cataract formation in the eye lens and whose 1-phosphate derivative is responsible for liver failure is Mannitol Sorbitol Inositol Galacticol 4. true about isoenzymes is same quaternary structure same enzyme classification with same numbers catalyse the same reaction same distribution in different organs 5. The reducing equivalents for fatty acid synthesis are derived from Urea cycle Glycolysis Kreb’s cycle Pentose phosphate pathway 6. An enzyme not involved in glycolysis is Enolase Phosphoglycero mutase Glycerophosphate dehydrogenase Aldolase 7. Histidine is the most important amino acid for buffering in normal conditions because Pka value is higher than pH Pka value is very low It regulates kidney acid-base balance Pka value is closer to pH 8. The common precursor of all three aromatic amino acids is ribose 5 phosphate Chorismate shilkimate Phosphoenolpyruvate 9. Thiamine deficiency causes decreased energy production because It is co-enzyme for pyruvate dehydrogenase It is required for the process of transamination It is co-enzyme for transketolase in pentose phosphate pathway It is a co-factor in oxidative reduction 10.

In the fasting state glucose is obtained from Liver glycogen Both None Muscle glycogen 16. Substrate for ATP synthase is- IMP AMP GMP ADP 17. Final common pathway of metabolism of carbohydrates, lipids an protein metabolism is none of the above Gluconeogenesis Glycogenesis TCA cycle 18. Immediate metabolic products during conversion of Fructus1-6 biphosphate to 2 molecules of pyruvate Glyceraldehyde-3-phosphate and 1,3-bisphosphoglycerate 3-phosphoglycerate and 1,3 biphosphoglycerate Glyceraldehyde-3-phosphate and dihydroxy-acetone phosphate Dihydroxyacetoone phosphate and 1,3 biphosphoglycerate 19. for glucose estimation in blood the mode of transport from a PHC to lab is potassium oxalate and NAF sodium citrate sodium fluoride EDTA 20. eukayotic plasma membrane is made up of all except carbohydrates lecithin triglycerides cholesterol Loading … Question 1 of 20
