ATP
: Organisms need energy for biological
processes
: ATP provides an immediate source of
: Energy is provided by ATP energy for biological processes
: ATP is a nucleotide derivative : ADP is converted into ATP during
: ATP = Adenosine triphosphate respiration
: ATP diffuses into the organelle that – by adding an inorganic phosphate
requires energy in the cell group in the following condensation
reaction:
: The energy in ATP is stored in the form
of the high energy covalent bonds : ADP + Pi ATP + Water
between the phosphate groups - catalysed by the enzyme ATP synthase
- this energy is released via hydrolysis : ATP synthesis takes place in both
reactions respiration AND photosynthesis
This reaction is reversible:
: ATP + Water ADP + Pi
: This is a hydrolysis reaction catalysed
by hydrolase
Made up of:
: The hydrolysis reaction is the one that
(1) Adenine – a nitrogenous base like
releases energy for all our cells’
the one found in RNA and DNA
processes
nucleotides
: When the bond between the
(2) Ribose – a pentose sugar like the
phosphate to the adjacent phosphate
one found in RNA
group is broken during the hydrolysis of
(3) 3 inorganic phosphate groups – they ATP
contain no carbon so are inorganic,
- the energy stored within that bond is
- represented by Pi in chemical released and can be used in metabolic
reactions reactions
: This energy tends to be a small,
manageable amount
: Adenine + Ribose have been
combined to make Aden-ose-ine = : The phosphate bond is broken using
adenosine water in the hydrolysis of ATP
: And 3 phosphate groups make - this releases energy, in a reaction
triphosphate which is catalysed by ATP hydrolase
: Adenosine triphosphate
