How does the RBC replenish NADH? With what essential enzyme? If enzyme was not there, what would occur?
12:00 AM | November 30, -0001Author: Adeleke
Pyruvate --> Lactate (Enzyme: Lactate DH) changes NAD+ --> NADH for glycolysis (lactate goes to liver) If Lactate DH not there, RBC would dieContinue reading
