Document Summary

Metabolism: all chemical reactions in which the body obtains and expands energy. Energy metabolism: coenzymes required in almost all metabolic reactions. Anabolism: glucose + glucose -> glycogen. Nutrient components used to produce energy: carbs, proteins, fats. How long does it take to produce energy in the body. Amino acids and glycerol converted to pyruvate and then to glucose. Acetyl coa build up and converted to ketones. 5 oz of wine, 10 oz of beer, 1 1/2 oz of liquor. Drinking on an empty stomach can also affect absorption rate. Liver cells are the first to receive alcohol after absorption. The liver can only metabolize 1 drink per hour. The alcohol will continue to circulate until the liver enzymes are ready to process it. Alcohol alters protein metabolism, including those important to the immune system. Brain cells can die with excessive exposure to alcohol. Drink a glass of water before every alcoholic drink.
