ATP and ADP Flashcards
1
Q
What are the 3 components of ATP?
A
Adenine, Ribose and 3 phosphate groups.
2
Q
What is the main function of ATP?
A
It is used to power most energy-requiring cellular reactions.
3
Q
What reaction takes place with ATP when a cell needs energy?
A
Hydrolysis
4
Q
What is the equation of the synthesis of ATP?
A
ATP + H20 –> ADP + P (+energy)
o It uses water so it is a hydrolysis reaction
5
Q
Which enzyme catalyses ATP hydrolysis?
A
ATP hydrolase
6
Q
What is the equation of the re-synthesis of ATP?
A
ADP + P (+energy) –> ATP + H20
7
Q
What enzyme catalyses this reaction?
A
ATP synthase
8
Q
How does ATP’s inorganic phosphate make other compounds more reactive?
A
Phosphorylation
