Document Summary
To keep the brain with a constant supply of glucose, glycogen is released between meals. Glycogen is stored in the muscles, but mainly in the liver, where it can be readily converted back into glucose when your circulating blood glucose levels are low. The glucose-glycogen balance is mediated to a large degree by the liver and a pancreatic hormone called insulin: glucose and glycogen balance: 1: pancreatic insulin secretin, uptake of glucose by cells. These rats who received cck ate more total meals than the controlled. Thus, the total food intake was actually the same for both groups: long-term energy storage, takes place in the form of fat (i. e. adipose tissue, fat has more than twice the energy that carbohydrates, like glycogen, have. When leptin levels rise, they act on receptors in the hypothalamus to reduce appetite and, consequently, food consumption decreases: leptin production is controlled by the ob gene.
