In the first step of glycolysis, the following two reactions are coupled: Reaction 1: glucose + P glucose-6-phosphate + HO AG +13.8 kJ/mol AG= 30.5 kJ/mol Reaction 2: ATP + HO ADP + P Answer the following four questions about the first step of glycolysis: 1) Is Reaction 1 spontaneous or nonspontaneous? nonspontaneous spontaneous 2) Write the net chemical equation. Use the same spelling as is shown in the reactions above. 3) Calculate the overall AG for the coupled reaction. AG= Number kJ/mol 4) Is the first step in glycolysis spontaneous (favorable)? yes no cannot be determined continued below... Ma 3
