Document Summary

Energy compromises various forms: heat, mechanical, electrical, chemical. Metabolism: the sum total of all the chemical reactions that go on in living cells. Energy metabolism includes all reactions by which the body obtains/expends energy from food; body releases energy, water, carbon dioxide and waste during process (review cell diagram); the liver cells are the most versatile/metabolically active. Anabolism: reactions in which small molecules are put together to build larger ones; reactions requiring energy. Carbohydrates: converts fructose and galactose to glucose, makes/stores glycogen, breaks down glycogen and releases glucose, breaks down glucose for energy when needed, makes glucose from some amino acids and glycerol when needed, converts excess glucose to fatty acids. Other: detoxifies alcohol, other drugs, and poisons; prepares waste products for excretion, helps dismantle old red blood cells and captures the iron for recycling, stores most vitamins/many minerals, converts vitamin d into intermediate metabolic form. Ex. of anabolic reactions: making of glycogen, triglycerides, protein.
