Chemical energy
energy stored in the bonds of molecules
Radiant energy

What are the three parts to an ATP molecule
adenine, ribose, and phosphate groups
What are the differences between ATP and ADP
ATP has three phosphate groups and is charged, ADP has two and is like a dead battery
When a phosphate is added to ADP to become ATP energy is
Stored
When a phosphate is lost from ATP to become ADP energy is
Released
