(3) Organisms……,.. � & Structures….

  • All living things complete cellular respiration (even plants).�
  • Living things use an organelle called the “mitochondrion” to complete respiration.

(4) What is the purpose?

  • The chemical potential energy from the bonds of glucose sugar, is transferred to the bonds of ATP.�
  • Type of energy stays the same, just transferred to a molecule cells can use (ATP).�
  • ATP is an energy storing and exchanging molecule.

THINK…� �Why would you get tired if you don’t eat enough sugar, or breathe in enough oxygen?

(5) Cellular Respiration & Matter

  • Matter is cycled in respiration:
    • The bonds holding together the Oxygen and Sugar molecules are broken.
    • Atoms are rearranged.
    • New bonds are formed in the newly produced molecules ATP, Carbon Dioxide, and Water.�
  • This is necessary to transfer the energy from sugar to ATP.
