Complimentary Processes

• 1. Photosynthesis and cell respiration are
  complimentary processes for cycling carbon
  dioxide and oxygen as well as transferring energy
  in ecosystems

ATP Molecule

• Molecule that stores energy in the bonds
  between phosphate groups.
• Adenosine Triphosphate

Chemical Bond
Adenine

ATP
Ribose
When a phosphate is removed from ATP, energy is
released from the broken bond.

ATP becomes ADP

• Removal of Phosphate from ATP ADP
• Addition of Phosphate to ADP ATP

Adenosine Diphosphate
