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...

The first reaction in glycolysis is the phosphorylation of glucose:
The first reaction in glycolysis is the phosphorylation of glucose:Pi+glucose⟶glucose−6−phosphate+H2OThis is a thermodynamically unfavorable process, with ΔG∘′=+13.8kJ/mol.Part AIn a liver cell at 37 ∘C the concentrations of both phosphate and glucose are normally maintained at about 5 mM each. =>theequilibrium concentration of glucose-6-phosphate = 1.2*10^-7 MPart BThis very low concentration of the desired product would be unfavorable for glycolysis. In fact, the reaction is coupled to ATP hydrolysis to give the overall reactionATP+glucose⟶glucose−6−phosphate+ADP+H+ΔG∘′ for the coupled reaction is -18.4 kJ/mol
