5. During step six of glycolysis glyceraldehyde-3-phosphate (G3P) is converted to 1,3- bisphosphoglycerate (1,3-BPG) and NAD+ is converted to NADH. (You can ignore the concentration of protons in the upcoming calculation.) G3P + P + NAD+ = 1,3 - BPG + NADH + H+ In the human erythrocyte, the concentration of G3P is 0.019 mm, the concentration of 1,3-BPG is 0.001 mM, the concentration of P, is 1.0 mm, and the ratio of NAD+ to NADH is 1000 to 1....
The reaction glyceraldehyde-3-phosphate + NAD++Pi→ 1,3 diphosphoglycerate + NADH+H+ has ΔrG∘′=6.3kJmol−1. If the standard reduction potential ε∘′ of NAD+ is -0.324 V and the reaction 1,3 diphosphoglycerate + ADP→ 3-phosphoglycerate + ATP has ΔrG∘′=−18.8kJ/mol, calculate the standard reduction potential ε∘′ for the reaction 3-phosphoglycerate +2e−+3H+→ glyceraldehyde-3-phosphate +H2O.
