Questions in photo 1) Glucose-6P (G6P) has a AGo of approximately -13.8 kJ/mole. Will the transfer of Glu-6Pto ADP to make Glu and ATP be spontaneous or not? (remember the hydrolysis of ATP toADP and Pi is -30.5 kJ/mole) What is the AG° of that reaction?2) Pyruvate has three carbons. Draw pyruvate and indicate which carbon is the mostoxidized and which is the most reduced.3) For the written reaction, which reactant is the oxidizing agent, and which is the reducingagent: Co + 2Fe*3 Co*2 + 2Fe+2
