• What do your cells need energy for?
• Movement
• Transport of molecules
• Production of proteins

• What do you need to do to get energy?
• Need to be able to make energy from the
  environment
• Need to store it for future use
• Need to be able to use it in a controlled manner

3
Where can you get energy from?

• Carbohydrates. It is broken down to release
  energy (glucose)

4
Energy Transport

• ATP Energy is stored in the chemical bonds
• Made up of
• adenosine
• adenine (nitrogen base) ribose (sugar) molecule
• 3 phosphate groups made by condensation
  reactions in the mitochondria
• Phosphate groups are negatively charged and take
  a lot of energy to bond them together

How do you get energy out of ATP?

• Hydrolysis
• WATER breaks the bond to the outer most phosphate
  group
• Energy is released when the bond is broken
• Molecule becomes ADP
• More energy can be released when a 2nd phosphate
  group is removed from ADP to make AMP

7
Loose ends.

• When ATP ? ADP, the ADP is recycled and made
  into ATP with the addition of a phosphate group.
