The diagram shows a model of the conversion between ATP and ADP. Which statement does the model support?

• ATP contains more energy than ADP.

• ADP contains more energy than ATP.

• ATP and ADP contain the same amount of energy.

Which statement explains the movement of energy through aerobic cellular respiration?

• Energy is absorbed as chemical potential energy is transferred from oxygen molecules to ATP molecules.

• Energy is released as chemical potential energy is transferred from oxygen molecules to ATP molecules.

• Energy is released as chemical potential energy is transferred from glucose molecules to ATP molecules.
