ATP Flashcards
What does ATP stand for
Adenosine triphosphate
What type of molecule is adenosine triphosphate
A phosphorylated macromolecule
How is ATP made
Organisms oxidise organic molecules to make atp
What is ATP made of
A nitrogen containing base - adenine,a pentose sugar - ribose and 3 phosphate
Are bonds between phosphates weak or strong
Weak
When the terminal bond is hydrolysed what happens
Energy is released this energy can be used by the cell/and or organism
What do enzymes aid
hydrolysis and production of atp
What does ATP hydrolase catalyse
The hydrolysis of ATP and ADP and an inorganic phosphate ion (Pi)
What can ATP synthase catalyse
The addition of a Pi to Dp to make ATP
how much energy does atp release at ones
It releases energy in small amounts
It is easily hydrolysed in one step
S
What can happen if bonds between phosphates are weak
They can be easily hydrolysed
What cell processes is ATP present in
Active transport,muscle contraction,cell sickling
What is the full name of atp
Adenosine triphosphate
What is ATP comprised o
3 phosphate groups,a base(adenine) and a sugar,ribose
All cells need oxygen,but how do they obtain it
Aerobic respiration
Fermentation
Anaerobic respiration
What happens when ATP is hydrolysed
It loses a phosphate
why is atp a good energy source in terms of it being hydrolysed
It is easily hydrolysed in one step to release ADP Pi and energy
how does atp regain energy after using it on reactions
When energy is released from reactions or by proton gradients it can be rapidly resynthesised from ADP and Pi
what does ATP do to other compounds to make them more reactive
It phosphorylates other compounds making them more reactive
what is ATP not able to leave through
It cannot leave through cell membranes
