Enolase converts 2-phosphoglycerate (2PG) to phosphoenolpyruvate (PEP). This reaction has a ΔG’o= + 7.5 kJ/mol, but the reaction occurs readily under normal cellular conditions. What is the ratio of [PEP]/[2PG] at equilibrium, at 25oC? In this case, If 2PG is present within the cell cytosol at a concentration of 6 x 10-3M and the concentration of PEP = 0.10 x 10-3M, what is the ΔG of the reaction at 37oC?

2. The first step in glycolysis is catalyzed by the enzyme herokinase: glucose + ATP glucose-6-P + ADP This reaction can be thought of as two coupled reactions (P is phosphate): (1) glucose + P + glucose-6-P (2) ATP + ADP + P For the overall reaction, AG" = -16.7 kJ/mol. For the hydrolysis of ATP (equation 2), AG = -310 kJ/mol. All reactions are performed at 37°C. (a) What is AGº for reaction 1? Iglucose - 6-11 if AG...
