GRE Biochemistry

Subjects : gre, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Actin - myosin - and other muscle proteins






2. Measure tendency for recombination (frequency) 1cM = 1% chance of being separated






3. 1e-14






4. Enter cells freely






5. Recruits RecA protein - inhibited by LexA - results in mutagenesis






6. Enzymes in Krebs cycle that produce NADH






7. Val - Leu - Ile - Ala - Met






8. = pKa+ log(B/A) - -log(Ka)






9. Vitamin B7 - cofactor that aids in CO2 transfer (carboxylase)






10. Converts oxaloacetate into phosphoenolpyruvate and carbon dioxide.






11. Catalyzes the addition of bicarbonate to phosphoenolpyruvate (PEP) to form the four-carbon compound oxaloacetate






12. FAD-2 - NADP-3






13. Can result in allele differences - suce as 3:1 and 1:3






14. An enzyme that removes a phosphate group from its substrate






15. Unwound - participates in the active transcription of DNA to mRNA products - site of RNA Pol II regulation






16. Measures physical base pair distance






17. Can undergo both lytic and lysogenic cycle






18. Possess an F plasmid that also includes some DNA taken from the bacterial genome. Sometimes it is formed by incorrect excision from the chromosome

19. When exons are arranged in multiple orders after removal of introns






20. Acetyl-CoA to malonyl-CoA - rate limiting step in fatty acid synthesis






21. PKa = pH






22. Makes Acetyl-CoA from pyruvate






23. RNA protein-complex






24. Irreversible reaction that require ATP first part of glycolosis






25. Recognizes and targets specific proteins to the endoplasmic reticulum in eukaryotes and the plasma membrane in prokaryotes






26. Serine protease that cleaves on c terminal side of aromatics






27. (His - Arg - Lys +) - (Glu - Asp -)






28. Catalyzes the transport of tRNA and mRNA down the ribosome in eukaryotes






29. Non-protein chemical compound that is bound to a protein and is required for the protein'S biological activity






30. Phe - Trp - Tyr - Gly - Pro






31. Only one carbon center is changed






32. Do not contain F factor






33. Circular and double stranded






34. Gene has multiple effects






35. Regulator of glycolysis when glucose is low by cleaving 2;6 BPG lowering PFK1 - opposite effect when glucose is high






36. Possess F factor integrated into the bacterial genome. After integration into the host chromosomal DNA - these plasmids possess portions of - or entire - F factor and portions of the bacterial genome.






37. Triglycerides - cholesterols - and phospholipids






38. Gene duplication






39. Failure of chromosome pairs to separate during meiosis






40. Possess F factor as a plasmid independent of the bacterial genome. The F plasmid contains only F factor DNA and no DNA from the bacterial genome.






41. Nuclear lamins - desmins - keratins - internexins (structure)






42. Gprotein association - exchanges GDP to GTP - converts AMP into cyclic AMP. Cyclic AMP binds to protein kinase A: Protein kinase A phosphorylates phosphorylase kinase. increases Ca which binds calmodulin proteins which then binds to phosphorylase kin






43. Secondary messenger - used for intracellular signal transduction - such as transferring the effects of hormones like glucagon and adrenaline - which cannot pass through the cell membrane. It is involved in the activation of protein kinases and regula






44. Donates electrons to form a bond such as N in amines and O in alcohols






45. It uncouples oxidative phosphorylation by carrying protons across the mitochondrial membrane - leading to a rapid consumption of energy without generation of ATP.






46. Preferable to hydrolysis (like in the breakdown of glycogen or starch - as in the example above) because glucose 1-phosphate yields more ATP than does free glucose when subsequently catabolized to pyruvate.






47. Neutralizes H2O2 - found in lysosomes






48. Ser - Cys - Thr - Gln - Asn






49. Phosphotransferase - is a type of enzyme that transfers phosphate groups from high-energy donor molecules - such as ATP -[2] to specific substrates. The process is referred to as phosphorylation -






50. The most important regulatory enzyme of glycolysis. It is an allosteric enzyme made of 4 subunits and controlled by many activators and inhibitors. PFK-1 catalyzes the important 'committed' step of glycolysis - the conversion of fructose 6-phosphate
