ATP Flashcards
1
Q
what is ATP
A
.A single molecule of adenosine triphosphate (ATP) is a nucleotide derivative
.formed from ribose, of adenine and three phosphate groups
2
Q
how does ATP provide energy
A
.by ATP hydrolase
.this is a hydrolysis reaction, involves addition of water
.ATP + water–>ADP+Pi+energy
3
Q
how is ATP synthesised? (made)
A
ADP+ Pi+energy—>ATP+ water
.reaction catalysed by ATP synthase
.condensation reaction, removal of water
4
Q
explain the useful properties of ATP
A
.The hydrolysis of ATP can be coupled to energy-requiring reactions within cells.( used directly without losing energy as heat)
. phosphorylating other compounds, often making them more reactive
.small and soluble
.immediate source of energy
