Given the following: [G3P] = 1.5x10-5M; [BPG] = 3.0x10-3M ; [NAD+] = 1.2x10-5M; [NADH]=1.0x10-4 ; [HPO42-]= 1.2x10-5 M; pH = 7.5 ; DGo=6.3 kJ/mol
Glyceraldehyde3-phosphate + NAD+ + HPO42- ---> 1,3-Biphosphoglycerate + NADH + H+
Predict whether this reaction will be spontaneous.
Answers: 3
concentration, we use the equation:![pH=-\log[H^+]](/tpl/images/0557/5671/cf945.png)
![7.5=-\log [H^+]](/tpl/images/0557/5671/95063.png)
![[H^+]=10^{-7.5)=3.1\times 10^{-8}M](/tpl/images/0557/5671/67b53.png)
= free energy of the reaction
= standard Gibbs free energy = 6.3 kJ/mol = 6300 J/mol (Conversion factor: 1kJ = 1000J)![25^oC=[273+25]K=298K](/tpl/images/0557/5671/0e82f.png)
= Ratio of concentration of products and reactants = ![\frac{[BPG][NaDH][H^+]}{[G_3P][NAD^+][HPO_4^{2-}]}](/tpl/images/0557/5671/dd6ba.png)
![[BPG]=3.0\times 10^{-3}M](/tpl/images/0557/5671/38e24.png)
