ATP
- structure
- phosporylated molecule
- adenine
- nitrogen-containing organic base
- ribose
- pentose sugar (5-C
ring structured
sugar mol)
- backbone
- phosphates
- chain of 3 phosphate groups
- how stores E
- ATP = nucleotide with
3 phosphate groups
- unstable bonds between
- low activation E
- easily broken
- release considerable
E amount when
broken
- hydrolysis of ATP
- ATP + H2O = ADP + Pi + E
- ADP = adenosine diphospate
- Pi = inorganic phosphate
- can phosphorylate
other compounds
- often makes them
more reactive
- catalysed by enzyme
ATP hydrolase
- can be coupled to
E-requiring
reactions within
cells
- E released for
use by cells
- synthesis of ATP
- resynthesised by
condensation of
ADP and Pi
- E supplied by respiration
- catalysed by enzyme ATP
synthase during photosynthesis
or respiration
