ATP Flashcards
1
Q
what does ATP stand for?
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
- ribose sugar
- adenine base
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 does ADP stand for?
A
adenosine diphosphate
7
Q
what is phosphorylation
A
reattaching the inorganic phosphate to ADP molecule and phosphate in a condensation reaction
8
Q
describe 5 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
