ATP Flashcards
1
Q
what is ATP?
A
adenosine triphosphate
2
Q
what is the role of ATP?
A
supplies 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 ADP?
A
adenosine diphosphate
7
Q
what is phosphorylation?
A
reattaching the ADP molecule and phosphate in a condensation reaction
8
Q
describe the properties of ATP
A
- small: moves in and out of cells easily
- soluble: processes requiring energy are in aq environment
- energy released in small quantities: no waste
- easily regenerated without energy
- unstable phosphate bonds: not long term energy store
