Answer:
1. Ribose (type of sugar found in ATP and ADP molecules)
2. The 3 phosphate groups (Energy is stored in the 3 phosphate groups and in order to bring the stored energy to use, the last phosphate bond breaks and energy is released)
3. ATP has a higher energy potential than ADP (This is cuz, ATP has 3 phosphate groups and ADP has 2 phosphate groups)
Hope this helps!
