Lactate dehydrogenase (LDHB) + gluconeogenic enzymes

1 reactions · 1 pathways

Clinical / pharmacological. Regenerates NAD+ anaerobically; LDHA deficiency causes exercise-induced myoglobinuria

What it does, reaction by reaction

1 reactions

Cori Cycle (lactate shuttle) Carbohydrate Metabolism · Cytosol (muscle) + liver

step 2 Irreversible/directional

Lactate -> pyruvate -> glucose (liver, 6 ATP equivalents)

Converts Lactate into Pyruvate

Notes

Net cost of 4 ATP equivalents per cycle, shifting the energy burden to liver. Metformin-associated and hypoxic lactic acidosis reflect failure of this arm.
