ATP Flashcards
1
Q
what is ATP made up of?
A
three phosphate groups, ribose, adenine group
2
Q
How is ATP formed?
A
Energy from glucose is used to form a phosphate bond between a molecule of ADP and inorganic phosphate, ATP synthase catalyses this
3
Q
How is ATP Brocken down?
A
ATP is hydrolysed into ADP and phosphate, ATP hydrolase catalyses this reaction
4
Q
why is ATP a useful molecule?
A
releases a relatively small amount of energy, so little is lost to heat
it is a one step reaction so releases energy instantaneously
I can phosphorylate other components so it makes them more reactive
it can be rapidly re-synthesised so its readily available
5
Q
why is it important ATP is continuously synthesised?
A
ATP cannot be stored, it is unstable so breaks down easily
