Which statement best distinguishes an energy transfer in respiration from a metabolic use of that transferred energy?
Respiration synthesises oxygen, which is then used to convert proteins into glucose
Respiration synthesises glucose, which is then used to break amino acids into nitrate ions
Respiration transfers energy, which can then drive enzyme-controlled synthesis reactions
Respiration transfers carbon dioxide, which can then drive uncontrolled synthesis reactions
