Question 1 (1 pt): In glycolysis, fructose 1,6-bisphosphate is converted to two products with a standard free-energy change (AG) of 23.8 kJ/mol. Under what conditions encountered in a normal cell will the free-energy change (AG) be negative, enabling the reaction to proceed spontaneously to the right? Under standard conditions, enough energy is released to drive the reaction to the right. a. b. The reaction will not go to the right under any conditions because AGo is positive. When there is...
