Metabolism

• Metabolism is the total of all the chemical processes that take place that take place in the body cells
• These chemical processes convert the food you eat into energy and materials needed for all life processes
• The smallest amount of energy that can sustain life is called basal metabolic rate (BMR)
• Catabolic reactions are metabolic processes
• Catabolic processes release energy
• Cellular respiration is an example of a catabolic reaction
• glucose + oxygen= water + carbon dioxide

  (C6H12O6 + 6O2= 6H2O + 6CO2)
• Anabolic reactions build complex substances from simpler ones
• Anabolic processes use energy
• Protein synthesis is an example of an anabolic process
• A nutrient is any substance in food that is used for growth, repair or maintaining the body; any substance required for metabolism
• There are six groups of nutrients; water, carbohydrates, lipids, proteins, minerals, and vitamins
