Under these conditions, various organs in your body secrete hormones:. These hormones act on cells of the liver, muscle and fat tissue, and have the opposite effects of insulin.
When you are not eating, or you are exercising , your body must draw on its internal energy stores. Your body's prime source of energy is glucose. In fact, some cells in your body, such as brain cells, can get energy only from glucose. The first line of defense in maintaining energy is to break down carbohydrates, or glycogen , into simple glucose molecules -- this process is called glycogenolysis. Next, your body breaks down fats into glycerol and fatty acids in the process of lipolysis. The fatty acids can then be broken down directly to get energy, or can be used to make glucose through a multi-step process called gluconeogenesis.
In gluconeogenesis, amino acids can also be used to make glucose. In the fat cell, other types of lipases work to break down fats into fatty acids and glycerol. These lipases are activated by various hormones, such as glucagon, epinephrine and growth hormone. Enter your email address to subscribe to our most top categories. Your privacy is important to us.

Aside from the moral implications, organ meats obtained from stressed and mistreated animals can cause all sorts of problems.
