ENERGY IS JUST LIKE MONEY!!!
What is needed in order to do anything?
• Energy
Where do we get our energy?
• the digestion of food
• The type of energy found in food is not
usable in our body…it must be changed.
How is energy used?
• Not all at once!!!
• Energy that is not used is stored as ATP
What is ATP?
• Adenosine TriPhosphate
(tri = 3)
• a molecule that stores
energy
Why is it important?
• this is the type of energy we
can use
• The type of energy found in
food is not usable in our
body…it must be changed.
ATP: The Energy Storing Molecule
ATP
How is energy stored into ATP?
• by the creating of bonds b/w PO4 groups
• ADP + P ATP
ATP
How is energy released from ATP?
• by the breaking of bonds b/w PO4 groups
• ADP + P  ATP
What are uses for energy?
1. To make more energy
2. Maintain homeostasis
3. Cell movement (cilia, flagella)
4. Bioluminescence: light produced by
organisms
