To calculate the free energy (delta G^0,) of a reaction, you can subtract the free energies of formation (G_f^0) of the reactants from those of the products. Given the following data, what will be true of this reaction? C_6H_12O_6 + O_2 rightarrow CO_2 + H_2O G_f^0: -917.30 -394.4 -237.2 The reaction will not require a catalyst to proceed. The reaction is not balanced, so you cannot calculate the change in free energy. The reaction will be endergonic. The reaction will...
The free-energy change, [delta] G, is positive for the cellular process of protein synthesis, so that this process is thermodynamically unfavorable even with the help of enzymes. How do cells still manage to synthesize proteins at such a high rate?
