NUCLEIC ACIDS Flashcards
1
Q
What forms ATP?
A
adenine- a nitrogen-containing organic base
ribose- a sugar molecule
phosphates- a chain of three phosphate groups
2
Q
What does ATP stand for?
A
Adenine triphosphate.
3
Q
How are the bonds between ATP?
A
Unstable so they have low activation energy and can easily be broken and when they are broken a lot of energy is released in living cells.
4
Q
What happens when ATP is hydrolysed?
A
It becomes ADP ( adenine diphosphate)
5
Q
How does ADP reform into ATP?
A
- An inorganic phosphate can be added to ADP to reform ATP. This reaction is catalysed by the enzyme ATP synthase
6
Q
What type of reaction is ADP to ATP?
A
Condensation.
7
Q
What are the three ways a phosphate molecule can be added to ADP?
A
- In chlorophyll containing plant cells during photosynthesis
- In plant and animal cells during respiration
- In plant and animal cells when phosphate groups are transferred from donor molecules to ADP
