(4) How Does It Cycle Matter Energy?

• ENERGY
• Transfers energy from the bonds of glucose to the
  bonds of ATP.
• MATTER
• Takes glucose and oxygen, breaks their bonds, in
  order to store energy in the newly formed ATP
  molecules.
• Makes un-useable sugar compounds, into energy
  storing molecules used by the cell.

(5) Connecting Photosynthesis
Respiration

• The glucose and oxygen produced in photosynthesis
  is necessary to begin cellular respiration.
• The carbon dioxide and water needed to begin
  photosynthesis, is made during cellular
  respiration.
