Chemical Energy & ATP
created by Mason Beadles
Summary
All Cells Need Chemical Energy
ATP (adenosine triphosphate) transports chemical energy within cells for metabolism. When ATP gets broken down, energy is released. ADP has three phosphate groups. When the third phosphate is removed and energy released, the molecule becomes ADP (adenosine diphosphate).
- ATP has three phosphate groups and is high energy
- ADP has two phosphate groups and is lower energy
Carbohydrates are the molecules most commonly broken down to make ATP.
- not stored in large amounts
- up to 36 ATP from one glucose molecule
Fats store the most energy.
- 146 molecules of ATP
Proteins are least likely to be broken down to make ATP.
- 36 molecules of ATP, similar to a sugar
- broken down into amino acids, used to build more proteins
Plants make their own food, but plant cells also need ATP. Through the process of Photosynthesis plants use energy from sunlight to make sugars. Plant cells break down the sugars to produce ATP, just like animal cells.
Some organisms live in places that never get sunlight. In Chemosynthesis, chemical energy, instead of light energy is used as a source to make food.
- Similar to photosynthesis
- Uses chemical energy instead of light energy.
- These organisms still need ATP for energy.
