N5S3 - ATP release, role and regen - 1.13 Flashcards
1
Q
How do cells get energy?
A
By releasing the chemical energy stored in food
2
Q
What is the role of ATP?
A
ATP is responsible for providing the energy required for cellular activites.
3
Q
What is ATP made up of?
A
1 adenosine molecule and 3 phosphate groups (Pi)
4
Q
How can the energy stored in ATP be released?
A
By breaking down ATP into adenosine diphosphate (ADP) and a phosphate group.
5
Q
How can ATP be regenerated?
A
ATP is regenerated by joining a molecule of ADP to a phosphate group using energy
6
Q
List 5 examples of cellular activities that require energy
A
- cell division
- protein synthesis
- active transport
- muscle cell contraction (in animal bodies)
- transmission of nerve impulses (in animal bodies)
7
Q
What is the word equation for the breakdown of ATP in cells?
A
ATP → ADP + Pi + Energy
8
Q
What is the word equation for the formation of ATP in cells?
A
ADP + Pi + Energy → ATP
