2.3 Energy And ATP Flashcards
1
Q
What are the 3 parts that make up ATP?
A
- adenine base
- ribose sugar
- 3 phosphates
2
Q
What is so special about the bonds between phosphate groups?
A
Unstable so have a low activation energy
3
Q
What happens when the bonds between phosphate groups break?
A
Release a considerable amount of energy
4
Q
Write the hydrolysis reaction of ATP to ADP
A
ATP +(H2O) -> ADP + Pi + E
5
Q
Which enzyme is used to hydrolyse ATP?
A
ATP hydrolase (ATPase)
6
Q
What sort of reaction is the conversation between ATP and ADP?
A
Reversible reaction
7
Q
Which enzyme is used to catalyse the reaction for the formation of ATP
A
ATP synthase
8
Q
give 5 uses of ATP
A
- metabolic processes
- movement
- active transport
- secretion
- activation of molecules
9
Q
why is ATP a good immediate energy source?
A
- release energy in small, manageable amounts
- break 1 bond in 1 reaction by DNA hydrolase
- can be regenerated
- lowers activation energy of phosphorylated molecules
10
Q
what can ATP not do?
A
be stored
