b) Given that the complete combustion of glucose releases 2870 kJ of energy per mole of glucose, calculate the % efficiency of cellular respiration in terms of ATP production under physiological conditions (ΔG for ATP hydrolysis = -50 kJ/mol). Assume the glycerophosphate shuttle is used with P:O ratios as above. c) What is the name of the amino acid that binds the proton in the rotor of ATP synthase?

Step 1
The energy released during the complete combustion of glucose is 2870 kJ/mol. The energy required for ATP hydrolysis is -50 kJ/mol. The efficiency of ATP production can be calculated using the formula: Efficiency = (Energy produced / Energy required) * Show more…

Energy from ATP hydrolysis drives many nonspontaneous cell reactions: $$ \begin{array}{r} \mathrm{ATP}^{4-}(a q)+\mathrm{H}_{2} \mathrm{O}(l) \rightleftharpoons \mathrm{ADP}^{3-}(a q)+\mathrm{HPO}_{4}^{2-}(a q)+\mathrm{H}^{+}(a q) \\ \Delta G^{\circ \prime}=-30.5 \mathrm{~kJ} \end{array} $$ Energy for the reverse process comes ultimately from glucose metabolism: $$ \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}(s)+6 \mathrm{O}_{2}(g) \longrightarrow 6 \mathrm{CO}_{2}(g)+6 \mathrm{H}_{2} \mathrm{O}(l) $$ (a) Find $K$ for the hydrolysis of ATP at $37^{\circ} \mathrm{C}$. (b) Find $\Delta G_{\text {rxn }}^{\circ \prime}$ for metabolism of 1 mol of glucose. (c) How many moles of ATP can be produced by metabolism of $1 \mathrm{~mol}$ of glucose? (d) If $36 \mathrm{~mol}$ of $\mathrm{ATP}$ is formed, what is the actual yield?
The hydrolysis of ATP can be summarized by the equation below: ATP + H2O -> ADP + Pi ΔG = -7.3 kcal/mol How many moles of ATP will a man hydrolyze in a day if he expends 2,300 kilocalories of free energy through this process? A) 73 mol B) 105 mol C) 315 mol D) 945 mol E) 16,790 mol
