ATP Flashcards
Full Name of ATP
Adenosine triphosphate
What is ATP formed from
Molecule of ribose
Molecule of adenine
3 phosphate groups
In ATP what is the name for the ribose and adenine together
Adenosine
Is ATP a nucleotide
Yes
How does ATP release energy + what type of a reaction
Small amount of energy to break covalent bond holding the last phosphate group.
But lots of energy is released
This is hydrolysis reaction water molecule is needed to break the bond
ATP + water
(+catalyst)
—> Adenosine diphosphate + phosphate group (Pi) + energy
Catalyst- ATP hydrolyse
What does Pi mean
Lower i tells us it’s an inorganic phosphate group
What happens to the ADP and phosphate that are released + catalyst
Recycled back to the ATP
ATP synthase
What reaction is adding the phosphate back onto the ADP
+ catalyst
Phosphorylation reaction
Catalyst- ATP synthase
Condensation reaction - water is released
What type of acid is ATP
Nucleic
What type of nucleotides is ATP
Phosphorylated
Which was is hydrolysis and condensation in ATP
Forward eg. To ADP + Pi HYDROLISIS ( water added)
Backwards E.g. back to ATP
CONDENSATION ( water released)
STRUCTURE OF ATP ( very important got wrong in test)
3 phosphates bonded to RIBOSE SUGAR to an adenine base
Describe induced fit model of enzyme action and how enzyme acts as a catalyst
Active site changes shape so it is complimentary to substrate
Enzyme-substrate complex formed
Reduces activation energy by bending bonds
How to stop reaction to prevent ATP from forming
Boil
ATP synthase enzyme denatures
