1. ATP
Energy for your cells!

2. What is ATP? ATP is a molecule that stores energy in its bonds.
It stand for adenosine triphosphate, and it looks like this:

3. Why ATP? You need energy to do all kinds of things: Breathe Grow Think
Move
Exercise

4. How do we make it?
ATP is made through the process of cellular respiration.
Energy from the food we eat is stored in the bonds of ATP.
ATP

5. What is it made of? ATP is made of 2 things:
A molecule of adenosine diphosphate (that has two Ps)
And a phosphate (one P)
We put these together through dehydration synthesis

6. How do we get the energy out?
To get energy out of ATP, we have to break the bonds.
The 3rd P is broken off (through hydrolysis)
Electrons are released, which gives us energy
Phosphate groups
Adenine
Ribose
Adenosine triphosphate
Hydrolysis
Adenosine diphosphate (ADP)
Energy

7. Then what? Now we have ADP and P again
They rejoin through dehydration synthesis to make more ATP

8. It just keeps going This is a cycle that keeps going
When you need energy, ATP bonds are broken to form ADP + P
When you store energy, ADP + P makes more ATP
