[Unit 1.6] ATP Flashcards
biological molecules
1
Q
what is the structure of ATP
A
adenine, ribose sugar, 3 phosphates
2
Q
what is the symbol for inorganic phosphate
A
Pi
3
Q
word equation for hydrolysis of ATP
A
ATP + H20 –> ADP + Pi + energy
4
Q
what enzyme catalyses hydrolysis of ATP
A
ATP hydrylase
5
Q
what is the word equation for the condensation of ADP
A
ADP + Pi + energy(from H+ ions) —–> ATP + H20
6
Q
what enzyme catalyses condensation of ADP
A
ATP synthase
7
Q
why is ATP better than glucose for energy
A
ATP releases less energy in smaller more manageable amounts
Hydrolysis of ATP is one step, so faster than glucose
8
Q
what is ATP used for
A
active transport
spindles contracting in anaphase
muscle contraction
conduction of nerve impulses
