- ATP
- formation
- condensation of ADP (adenosine diphosphate) and Pi (inorganic ion)
- catalysed by ATP synthase
- during respiration and photosynthesis
- structure
- 1 molecule of ribose and adenine and 3 phosphate groups
- adenosine triphosphate
- Hydrolysis
- ATP is an immediate source of energy
- energy in ATP is stored in high energy bonds between phosphate groups
- catalysed by ATP hydrolase
- hydrolysis can be 'coupled' to other energy requiring reactions
- energy released can be direct used to make the coupled reaction happen instead of being lost as heat
- Pi released can be added to another compound (phosphorylation) which makes the compound more reactive
- ATP is an immediate source of energy
- role
- once made ATP diffuses to the part of the cell that needs energy
- metabolic reactions
- active transport
- movement
- formation
