The conversion of AMP (adenosine monophosphate) to adenosine and inorganic phosphate (Pi) is the least energetic among the options. This is because it involves the removal of only one phosphate group without the transfer of additional phosphate groups, unlike the other reactions that involve the transfer or removal of two phosphate groups (as in ATP to ADP or ATP to AMP), which typically release more energy.
