19.5: Effect of Concentration on Enzyme Activity

WebpH doesn't affect the Nernst equation. But the Nernst equation predicts the cell potential of reactions that depend on pH. If H + is involved in the cell reaction, then the value of E will depend on the pH. For the half-reaction, 2 H + + 2 e − → H 2 , E ∘ = 0 According to the Nernst equation, E H + / H 2 = E 0 − z F R T l n Q = − z F ... WebLysosomal enzymes have low activity at the pH of the cytosol, which may serve as "insurance" for the cell: even if a lysosome bursts and spills its enzymes, the enzymes will not begin digesting the cell, because they will no longer have the right pH to function. ^5 5 Feedback inhibition of metabolic pathways
