Trivia. 1  In the book, Oh told Tip to call him J. Lo, thinking it was a common name. Tip constantly refered to him by name, with everyone assuming she meant the actress. 2  Despite being a protagonist, he bares a slight resemblance to Gallaxhar, as both are aliens who have stretchy arms as well as squid-like feet.
Glycogenolysis, process by which glycogen, the primary carbohydrate stored in the liver and muscle cells of animals, is broken down into glucose to provide immediate energy and to maintain blood glucose levels during fasting. Glycogenolysis occurs primarily in the liver and is stimulated by the hormones glucagon and epinephrine (adrenaline).
Glucagon, made by islet cells (alpha cells) in the pancreas, controls the production of glucose and another fuel, ketones, in the liver. Glucagon is released overnight and between meals and is important in maintaining the bodyâs sugar and fuel balance. It signals the liver to break down its starch or glycogen stores and helps to form new glucose units and ketone units from other substances. It also promotes the breakdown of fat in fat cells.
