Which student, if either, is most correct in their claim regarding the ATP/ADP cycle? A. Brianna's claim is correct - the removal of a phosphate group (or the breaking of
a chemical bond) supplies a great deal of energy from the cell and the ATP/ADP process is not continuous.

B. Neither student is completely correct. Oscar is correct in that this process is a
cycle and Brianna is correct in that the removal of the phosphate group supplies the most energy

C. Oscar's claim is correct - the addition of a phosphate group (or the making of a
chemical bond) supplies a great deal of energy from the cell and the ATP/ADP
cycle is continuous.

D. Both students are correct - Oscar's claim is correct for the process of
photosynthesis and Brianna's claim is correct for the process of cellular
respiration.
