ATP Flashcards
what proportion of energy is ATP compared to a glucose molecule
ATP has 1/32 the energy in a glucose molecule
what stores does ATP use
thermal
kinetic
chemical
why does ATP have such a small amount of energy
so it can be used in manageable bursts for cells
where is ATP made and used
made in the cell, used in that cell immediately
what transfers does ATP use
light and electrical
name some things ATP is used for
metabolic reactions
movement
active transport
what are the components of an ATP molecule
adenine (the base)
ribose (pentose sugar)
3 phosphate groups
what is the chemical nae for ATP
adenosine triphosphate
how is ATP energy released
it is hydrolysed (water molecules added) to break a bond - releasing lots of energy
turning ATP into ADP (adenine diphosphate)
what enzyme hydrolyses ATP
ATPase
what are the advantages of ATP
fast source of energy
small bursts
mobile and transports chemical anywhere in the cell
disadvantages of ATP
is made and used in the same cell - cant be transported out of the cell
its too volatile and cant be stored
what does ATP provide energy for
metabolic processes
movement
active transport
activation of molecules
bioluminescence
phosphorylation of glucose
