Compare and contrast the short- and long-term energy reservoirs of the body.
What will be an ideal response?
Liver cells convert glucose to glycogen, which is then stored in the liver and the muscles. This short-term reservoir is used to fuel the brain and is rapidly depleted. Glucagon secretion catalyzes the conversion of glycogen to glucose. The long-term energy reservoir is in fat cells and is composed of triglycerides. Glycerol is a major product of triglyceride metabolism and is converted to glucose in the liver.
