These questions are very challenging please help me!
Case study; However, depending on the radiotracer used, PET provides diagnostic information based on other types of metabolic activity, such as amino acid1 metabolism, cell proliferation, and tissue hypoxia.2 For example, amino acids and amino acid analogs3 have been labeled with fluorine-18 or carbon-11 and have been reported to be superior to FDG for imaging of brain tumors (Pirotte et al. 2004, Nariai et al. 2005, W. Chen et al. 2006). Another class of PET tracers that has shown promise is radiolabeled thymidine analogs (Shields 2006). The use of these tracers is based on the hypothesis that they mimic the biological behavior of thymidine, and thereby provide a measurement of DNA synthesis and cell proliferation in vivo. By extension, these tracers provide an accurate measure of tumor growth
1. Generate the five molecules of the pentose-phosphate pathway
2. How does the Pentose Phosphate Pathway become an intermediate process in the Xylulose-5-phosphate utilization reactions?
3. justify/falsify; the step where glyceraldehyde-3-phosphate is oxidized is substrate-level phosphorylation.
4. Site the synthesis reaction for the Glycolysis zone
5. Explain or calculate 24 ATP molecules from the generation of the TCA cycle
6. Explain the first step of the TCA cycle, which lay foundation for the lipid metabolism
7. The enzymes present in glyoxylate cycle are which type of enzymes? Elaborate
8. Falsify; (PEP) is converted to oxaloacetate by the enzyme PEP deaminase.
9. Relate the basic components of oxidation of carbohydrates, lipids and amino acids to the whole TCA cycle
10. Why are the Protein molecules not able to be passed into the cell for energy production?
