synthesis
transport
movement
2
Q
structure of ATP
A
3 phosphate groups
ribose sugar
adenine base
3
Q
how is energy released by ATP?
A
hydrolysis reactions
4
Q
ATP + water
A
ADP + P + energy
5
Q
why are fats and carbs better stores of energy?
A
they are far more stable
the phosphodiester bonds in ATP are very instable
6
Q
what is phosphorylation?
A
the reattaching of a phosphate group to ADP
7
Q
properties of ATP
A
small
water soluble
releases energy is small amounts
easily regenerated
8
Q
