- AATP
- Bsynthase
17How does ATP differ from other energy storage molecules, such as starch or glycogen?
- AIt's a less stable molecule, so not used for long-term storage.
- BIt is known as the universal energy currency because it releases energy in greater quantities.
- CEnergy release from ATP is a multi-step process.
- DATP is a polymer which has only one type of monomer.

- AHydrolysis
- BCondensation
