How many ATP's could theoretically be produced when a granule of glycogen is hydrolyzed to glucose subunits that then enter glycolysis and respiration? B. Glycogen metabolism is regulated by insulin and glucagon. Both of these hormones are produced by the pancreas and act as signals that interact with a transmembrane receptor on target cells. Intracellular events involve protein kinase A that activates or inactivates enzymes involved in glycogen synthesis or degradation. Briefly describe what protein kinase A does to these proteins.Please be clear in your explanation. I need to figure out how to find the pI of the amino acid. Thank you!Does this calculation look correct? My goal isto have a target mass of 10 µg of my protein with a total volume of 30 µl. Protein was measured and found to have a concentration of at 308.35 µg/ml Recall, mass = concentration * volume 10 µg = 308.35 µg/ml * V V = 0.01 mg/ 0.30835 mg/mL = 0.032430679 mL = 32.43067942 µL Note: cannot measure this amount; two dilutions required. Dilute by 1/40: measure 2.5 µl of protein at 0.30835 µg/µl and add it to 97.5 diluent to prepare a solution of protein at 7.71 mg/ml. This diluted sample will be used further. Mass = concentration * volume 10 µg = 7.71 mg/ml * V V = 0.01 mg/ 7.71 mg/ml = 1.3 µL Therefore, will measure 1.3 µl of protein at 7.71 mg/ml and add it to 28.7 µl of diluent.

- Question 11. // Hint: Isoelectric focusing separates proteins based on their pI values, and can separate proteins that only differ by a net charge of ±1.±1. Recall that an amino acid residue with a negatively charged R group has a relatively low isoelectric point (pI) where it has zero net charge. Likewise, an amino acid residue with a positively charged R group has a relatively high isoelectric point (pI) where it has zero net charge. Order from Low pH to High pHQuestion: 1.
