Part 1 (2 points)See Hint (A) Phosphorylation of glucose to produce glucose-6-phosphate has ΔG˚' = ? kJ/mol without the use of ATP. (B) Coupling phosphorylation with ATP hydrolysis gives ΔG˚' =? kJ/mol. Part 2 (1 point) Using concentrations of intermediates found in a cell, the phosphorylation of glucose using inorganic phosphate has ΔG' = 19.7 kJ/mol, while phosphoryl transfer from ATP (ATP investment) results in ΔG' = -34.5 kJ/mol. What does this tell you about the values of Q and...
