- The following diagram shows the ATP hydrolysis reaction. During ATP hydrolysis, the phosphoanhydride bond shown is broken, resulting in the production of ADP and inorganic phosphate. Phosphoanhydride bond HO- H OH OH OH Water ОН ОН ATP NH₂ новова OH OH ОН ОН ADP You have two hypotheses about this reaction: (1) The hydrolysis of ATP has a positive standard free energy change (AGO) (2) The hydrolysis of ATP has a negative standard free energy change (AG) NH2₂ + Phosphate To try and distinguish between your hypotheses, you make some observations about this reaction. Determine whether each observation below is consistent with hypothesis 1 only, hypothesis 2 only, or both hypothesis 1 and hypothesis 2. Question 76 Observation 1: The hydrolysis of ATP cannot occur spontaneously in a cell. O This observation is consistent with hypothesis 1 only.

Given the information below and using what you know about ATP Synthase and the proton motive force, calculate the overall AG and determine if the coupled reaction is favorable overall. Note that you do not need to worry about intermediates like we did for the class example. ADP + Pi → ATP has a AG = 7.3 kcal/mol 2 moles of protons traveling back down their gradient across the inner mitochondrial membrane has a AG = -10.28 kcal/mol %3D O a. Overall AG = -17.58 kcal/mol, favorable overall O b. Overall AG = -2.98 kcal/mol, favorable overall %3D O c. Overall AG = 2.98 kcal/mol, unfavorable overall O d.
