THE MITOCHONDRION

• The Power Plant
• of the Cell

Note One structure is called a mitochondrion.
Two or more are called mitochondria.
2
The Plant Cell

• The Mitochondrion
• Where food is burned to release energy
• Needs oxygen
• Site of Cellular Respiration

3
Your Function

• Site of Cellular Respiration
• Use oxygen to break up food molecules (glucose)
  releasing energy.
• Release carbon dioxide and water as waste
  products.

4
What Happens Here

• The Respiration Reaction
• glucose oxygen ? carbon dioxide water
  energy

C6H12O6 6O2 ? 6CO2 6H2O energy

Job Description

• Get 6 oxygen (O2) molecules from the cytoplasm.
• Get 1 glucose (C6H12O6) molecule from the
  cytoplasm.
• Pull the glucose molecule apart.
• Turn your light on to show the release of energy.
• Take the carbon atoms and make as many molecules
  of carbon dioxide (CO2) as you can.
• Take the hydrogen atoms and make as many
  molecules of water (H2O) as you can.
• Have the cytoplasm carry the carbon dioxide
  molecules to the cell membrane where they can be
  released.
• Have the cytoplasm carry the water molecules to
  the vacuole for storage.
