Respiration

• Respiration 


  Breaking down of glucose in cells to release energy (in the form of ATP)
• ATP


  Adenosine Triphosphate

  molecule that stores energy
• Breathing


  the process of inhalation and exhalation including exchange of gases in the lungs
• Breathing is needed to get oxygen into the blood and this oxygen can then be used for respiration
• Energy in the body is released by the breakdown of glucose and fatty acids.
• Aerobic respiration


  respiration with oxygen
• Anaerobic respiration

  Respiration without oxygen
• Respiration takes place in every cell of the body (other than red blood cells) in mitochondria
• Mitochondria - plural

  Mitochondrion - singular
• What type of respiration occurs when oxygen is present?

  Aerobic respiration
• Where does aerobic respiration occur in living organisms?


  In the mitochondria
• Why is aerobic respiration preferred by organisms?

  Because more energy is released and no lactic acid is produced
• What is the word equation for aerobic respiration?

  Oxygen + Glucose → Carbon Dioxide + Water + 38 ATP
• How many ATP molecules are produced during aerobic respiration?


  38 ATP
• What are the reactants in the process of aerobic respiration?


  Oxygen and Glucose
• What are the key differences between aerobic and anaerobic respiration?

  • Aerobic respiration requires oxygen; anaerobic does not.
  • Aerobic produces more ATP (38 ATP); anaerobic produces less (2 ATP).
  • Aerobic produces carbon dioxide and water; anaerobic produces lactic acid or ethanol.
