Document Summary
Case study: soon-yi part ii: accessing glycogen stores: glycogen, glycogenolysis: role of adrenaline and glucagon, glycogen phosphorylase, differences muscle vs. liver. As soon-yi begins to run over the sand, her existing blood glucose cannot readily sustain muscle glycolysis: she needs more fuel for glycolysis, and her muscle glycogen will provide this. Glycogen = a polymer of glucose is found in granules in muscle and liver. Has (1 4) links as well as (1 6) branch points: store glucose to support sugar in muscle and liver, structurally similar to mylopectin, but more branched. Glycogen is a polymer of glucose found in cytoplasm and in granules in. Fat is energy rich, but efficiency goes down if just using fat. Soon-yi has not eaten for 10 hours: as her blood glucose level dips, she releases two hormones into her blood: if blood sugar goes down, body responds.
