QUESTION 19 In glycolysis, fructose 1,6-bisphosphate is converted to two products with a ∆G'° of 23.8 kJ/mol. Under what conditions encountered in a normal cell will the free-energy change (∆G) be negative, enabling the reaction to proceed spontaneously to the right? A. Under standard conditions, energy is released to drive the reaction to the right, B. the reaction will not go to the right spontaneously under any conditions because the ∆G'° is positive, C. the reaction will proceed spontaneously to...
