Why is fluorodeoxy glucose used in PET scans? And how does it indicate the presence of cancer cells?

In a Word document, first create a separate Title Page that contains the name of
the project, along with your name and the date. Then, answer the questions below:
1. Summarize the difference between cancer cells and normal cells, in terms of
metabolic activity, in your own words. Be sure to address the presence or
absence of oxygen, pyruvate, and lactate.
2. PET scans are used as a diagnostic for cancer cells. Describe how PET scans
work in your own words.
3. Why is fluorodeoxy glucose used in PET scans? And how does it indicate the
presence of cancer cells?
4. In the above articles and videos, there is a discussion of the role of pyruvate
and lactate. Draw the two structures and circle on your drawings exactly
where the two structures differ. Submit a photo of your drawing with your
student ID card visible with your Project. Make sure your image is clear. If
the image can not be read, it can not be evaluated.
5. Draw the reaction that can occur to convert one to the other . Show how NADH is involved in the reaction and give the name of any enzyme. Submit a photo of your drawing with your student ID card visible with your Project. Make sure your image is clear.
