Understand the role of the liver in glucose metabolism: The liver stores glucose in the form of glycogen and releases it into the bloodstream when needed.
Identify the hormones involved in regulating blood sugar levels: Insulin, glucagon, cortisol, and thyroxine are key hormones that influence glucose metabolism.
Examine the function of insulin: Insulin is responsible for lowering blood sugar levels by facilitating the uptake of glucose into cells and promoting glycogen storage in the liver.
Explore the role of glucagon: Glucagon is a hormone that stimulates the liver to convert stored glycogen into glucose and release it into the bloodstream, thereby increasing blood sugar levels.
Consider the effects of cortisol and thyroxine: Cortisol can increase blood sugar levels by promoting gluconeogenesis, while thyroxine primarily affects metabolism but does not directly stimulate glucose release from the liver.
