a)
ADP
b)
H2O
c)
NADPH
d)
pyruvic acid
10.
Is ADP or ATP more like a fully charged battery, and why?
a)
ADP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
b)
ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
c)
ADP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
d)
ATP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
