生物化学 文本文档（Biochemistry text document） Review of Biochemistry over the years 2006-11-11 10:3 [large, medium and small] The limiting enzyme in the synthesis of 1. bile acids is 7- alpha hydroxylase (2002) 2. cholesterol can not be converted into: bilirubin (2005) 3. the major form of deamination in muscle is the purine nucleotide cycle (1999) The role of the 4. coenzyme in the enzymatic reaction is to act as a transport carrier (2000) 5. the correct description for hexokinase follows: activating glucose to participate in the reaction (2001) 6. in the process of glycolysis,, an enzyme that produces NADH and consumes inorganic phosphate, is collected and sorted out as follows: 3- phosphate dehydrogenase (2002) 7. urea synthesis in the liver is: mitochondria and oars (2003) 8., the horizontal spread of the virus refers to the virus: the spread of individual populations (2004) 9. the end product of purine nucleotides in vivo is uric acid (2005) The 10. is: transaminase coenzyme pyridoxal phosphate (1999) 11.. The key enzyme of glycolysis is -1 (2001) 12. the bases of nucleic acid molecules are mainly 5 species (2001) 13. for the description of the enzyme active center, it is correct to include the binding group and the catalytic group (2003) 14., for the reorganization of DNA technology medical education network collection and collation of the narrative, not correct is: into the cells of recombinant DNA can express target protein (2004) 15. about the enzyme K value, the correct is: Km value is equal to half of the maximum reaction speed of the substrate concentration (2005) 16., the key enzyme in cholesterol synthesis is HMGCoA reductase (1999) 17. acetyl CoA of synthetic fatty acids mainly comes from the catabolism of sugars (2000) 18. the raw materials for the synthesis of hemoglobin are CoA, glycine, and Fe2+ (2001) 19. steroid hormones are: adrenal cortical hormone (2004) 20. the skeletal components of the polynucleotides are pentose and phosphoric acid (2000) 21. the
