ATP Flashcards
1
Q
describe the structure of ATP.
A
nucleotide derivative of adenine with 3 phosphate groups.
2
Q
explain the role of ATP in cells.
A
ATP hydrolase catalyses ATP - ADP + Pi.
phosphate group phosphorylates compounds to make them more reactive.
3
Q
how is ATP resynthesised in cells?
A
ATP SYNTHASE catalyses condensation reaction between ADP + Pi during photosynthesis and respiration.
4
Q
explain why ATP is suitable as the ‘energy currency’ of cells.
A
high energy bonds between phosphate groups.
small amounts of energy released at a time = less energy wasted as heat.
single step hydrolysis = energy available quickly.
readily synthesised.
