respiration

• Respiration is the controlled release of energy from food with or without using oxygen. It is an essential characteristic of all living things
• aerobic respiration is the controlled release of energy from food using oxygen
• anaerobic respiration is the controlled release of energy from food without the use of oxygen
• glucose + oxygen = carbon dioxide + water vapour + energy (ATP)
• C6H12O6 + 6O2 —> 6CO2 + 6H2O + ATP (38)
• aerobic respiration has a 40% efficiency the other 60% is lost as heat, the process used to regulate body temperature is respiration
