1. The document discusses the roles of the liver and insulin and glucagon in processing glucose from food. Insulin transports glucose from the bloodstream into liver cells for storage as glycogen, while glucagon mobilizes glucose from glycogen stores and releases it into the bloodstream.
2. When insulin is "fired" from its job, glucagon is hired to break down glycogen and release glucose.
3. The liver has additional functions beyond regulating glucose, including producing bile, storing iron, synthesizing proteins, breaking down amino acids via deamination, and detoxifying the body by breaking down toxins like alcohol.
