8) The first step in glucose metabolism via glycolysis: Glucose + ATP glucose-6-phosphate + ADP is catalyzed by the enzyme hexokinase. This reaction has a standard free energy change ( AGC) of -40 kcal/mol. A) What would the free energy change (AG) of this reaction be under physiological conditions, i.e., 55 mm glucose, 5 mM ATP, 0.1 mM glucose-6-phosphate, and 1 mM ADP assuming a temperature of 25C. (Hint: The gas constant, R, is equal to 1.98 cal/mol K) (5 points)
