Question
Your colleague has obtained a sample of muscle phosphorylase that is known to be relatively inactive. She has approached you for advice on how to set up an appropriate assay. She has the following items available, not all of which are appropriate for this study. Help her out by selecting the items that she should use and what their purpose is in the assay, and then explain why each of the other items would not be useful.

1. 100 μM AMP
2. 1.0 mM ATP
3. 100 μM glucose
4. 10 mM glucose 6-phosphate
5. Unbranched glycogen
6. Branched glycogen
7. 50 mM HEPES buffer, pH 7.5
8. 50 mM potassium phosphate buffer, pH 7.5

Write out a short explanation for each of the above items, and upload your answers by the due date.
