Cell Energy

Which statement best explains the structure and function of ATP?

• When bond Z is formed, energy is released for cellular activities.

• When bond Z is broken, energy is released for cellular activities.

• When bond Y is formed, energy is stored for cellular activities.

• When bond Y is broken, energy is stored for cellular activities.

Which statement best describes the relationship between ADP and ATP?

• The addition of thymine to adenine will decrease the energy to form ATP from ADP.

• The substitution of deoxyribose for ribose will provide energy to form ATP from ADP.

• The addition of a phosphate group to ADP forms ATP and results in a net gain of energy.

• The subtraction of a phosphate group from ADP forms ATP and results in a net loss of energy.
