• Triphosphate

• Ribose

Which option matches the part of the molecule labeled #2?

• Adenine

• Carbon

• Nitrogen

• Triphosphate

• Ribose

Which option matches the part of the molecule labeled #3?

• Adenine

• Carbon

• Nitrogen

• Triphosphate

Between which parts of the molecule must the bonds be broken to form an ADP molecule? (Choose A, B, or C for your answer).

• A

• B

• C

Is ADP or ATP more like a fully charged battery, and why?

• ADP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.

• ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy

• ADP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.

• ATP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.

Which option matches the part of the molecule labeled #6?

• Energy stored

• Energy released

• ATP Molecule

• ADP Molecule
