Name things that run on batteries?
Then tell me what molecule inside of your body acts like batteries.

3. ENERGY ATP - Adenosine Triphosphate
Stores chemical energy released from cellular respiration
releases energy for life processes by losing one phosphate to create ADP (Adenosine diphosphate)
Stores energy released from food by adding a phosphate to ADP

8. Law of conservation of energy
Energy can neither be created nor destroyed.
It can only be transformed into different forms.
