74) Several steps in glycolysis are highly regulated. Overallreactions of glycolysis are regulated by insulin and glucagon. Whatdo they do?
..
75) Calcium ion (Ca++) stimulates isocitrate to a-ketoglutarateand a-ketoglutarate to succinyl CoA reactions. Where does Ca++ comefrom?
..
76) Number of amino acids can participate in energy metabolism.How do protein metabolism and carbohydrate metabolismintersect?
..
77) During fasting, glycogenolysis starts first and then largeamount of fatty acids are released from adipose tissue into theblood. The liver receives large part of it and use for b-oxidation.As a result of b-oxidation, how gluconeogenesis is regulated?
..
78) Glycogenolysis is regulated by insulin to glucagon ratio.The enzyme that degrades glycogen is active when it isphosphorylated by another kinase that is active when phosphorylatedalso by PKA. How does high and low insulin-to-glucagon ratioinfluence degradation of glycogen?
