Document Summary
Carbohydrate metabolism: glycogen synthesis and breakdown, glycolysis and fermentation, gluconeogenesis, pentose phosphate pathway. She has a big race coming up the next day. Because she wants to increase her glycogen intake: spaghetti and caesar salad, hamburger and onion rings, veggie soup, killer chilli. Her liver and muscle is going to run out of glycogen. First you move the phosphate from the 6 position to the 1 position. Take glucose 1 phosphate and add glucose unit onto glycogen. Suppose g6p allosterically regulate both glycogen synthase and glycogen phosphorylate in skeletal muscle. Answer: a) synthase activated and phosphorylase activated, b) synthase inhibited and phosphorylase inhibited, c) synthase activated and phosphorylase inhibited. When you turn one on you are likely to want to turn the other one want them active at the same time so however they are regulated, the regulation will probably be opposite.
