| What is ATP | - Nucleotide
- Adenosine triphosphate
- Phosphorylated macromolecule |
| Structure of ATP | - Ribose
- Phosphates
- Adenine |
| Properties of ATP | - Bonds between phosphate groups are unstable and are easily broken, so have low activation energy |
| What ATP does | - Its an immediate energy source
- Not a good long-term energy store |
| Detailed function of ATP | - Releases small amounts of energy
- So there's a controlled release of energy
- No excess energy released |
| Some roles of ATP in cells | - Metabolic processes
- Movement, energy for muscle contraction
- Active transport |
| How ATP stores energy | - When bonds break they release a large amount of energy
- Hydrolysis is used to convert ATP to ADP (adenosine diphosphate) and also forms an inorganic phosphate
- Single hydrolysis reaction
- This reaction is catalysed by ATP hydrolase |
| Synthesis of ATP | - The reaction of converting ATP into ADP is a reversible reaction
- This reversible reaction involves condensation catalysed by the enzyme ATP synthase |
