Energy systems — ATP, glycolytic, aerobic

What you'll learn

1. 1

   Imagine your body is like a phone battery — it needs energy to work. That energy comes from a molecule called ATP (adenosine triphosphate).

2. 2

   What is the name of the molecule that gives your body energy?

3. 3

   Think of ATP like a rechargeable battery. When it's full, it has 3 'phosphate' bits. When you use it, one bit pops off and releases energy.

4. 4

   Let's look at the 3 energy systems — like 3 different ways to recharge your battery.

5. 5

   Drag each activity to the correct energy system it uses most.

6. 6

   Which energy system uses oxygen and lasts the longest?

7. 7

   During a 400m run (about 60 seconds), which system is working hardest?
