ATP Flashcards
1
Q
what is ATP?
A
adenosine triphosphate
2
Q
what is the role of ATP?
A
supply energy for synthesis, transport and movement in cells
3
Q
describe the structure of ATP
A
- 3 phosphates (circles)
- ribose sugar (pentagon)
- adenine (pentagon and hexagon)
4
Q
what is the equation for the breakdown of ATP into energy?
A
ATP + H2O –> ADP + Pi + energy
5
Q
what type of reaction is the breakdown of ATP?
A
hydrolysis
6
Q
what is the equation for the formation of ATP
A
ADP + Pi –> ATP + H2O
7
Q
what type of reaction is the formation of ATP?
A
condensation
- uses enzyme ATP synthase
8
Q
what is ADP?
A
adenosine diphosphate
9
Q
describe the properties of ATP
A
- small, moves in and out of cells easily
- water soluble, energy-requiring processes happen in aqueous environments
- energy released in small quantities, so energy isn’t wasted as heat
- easily regenerated, can be recharged with energy
- unstable phosphate bonds, not long term energy store
