2. Which of the following best explains how the structure of ATP helps provide energy to the cell? (Points : 1)
ATP contains energy in the chemical bonds between its phosphate groups.
ATP contains energy in the chemical bonds between adenine and ribose.
When the molecules that form ATP bond together, energy is produced.
Many ATP molecules bond together to produce energy.
3. How is the energy that is carried in an ATP molecule released to provide usable energy? (Points : 1)
The sugar ring breaks away from the ATP molecule.
A sugar ring attaches to the ATP molecule.
The bond holding the last phosphate group breaks.
A phosphate group attaches to the ATP molecule.
