Lactate production is buffered intracellularly, e. Glycolysis coupled with lactate acidodis is neutral in the sense that it does not produce excess hydrogen cations; however, pyruvate production does produce them. Unsourced material may be challenged and removed.
This is incorrect, as cells do not produce lactic acid; pyruvate is converted directly into lactate, the anionic form of lactic llactica.
In some situations, hemofiltration purification of the blood is temporarily required. Can acute overdose of metformin lead to lactic acidosis? Diabetes Obes Metab, 3pp.

In the anoxic conditions where anaerobic respiration is dominant, calcium levels in the blood plasma increase. The net result is ATPthe lactoca carrier used by the cell for metabolic activities and to perform work, such as muscle contraction.
Lactic acidosis – Wikipedia
Measures for preventing lactic acidosis in ruminants include avoidance of excessive amounts of grain in the diet, and gradual introduction of grain over a period of several days, to develop a rumen population capable of safely dealing with a relatively high grain intake.

Lactic acidosis is an uncommon side effect of metformin use, which is more likely to arise in patients with certain predisposing factors. With depletion of muscle glycogen, the loss of ATP causes the muscles to grow stiff, as the actin-myosin bonds cannot be released.
In particular, during the capture of large crocodiles, the animals’ use of their glycolytic muscles often alter the blood’s pH to a point where they are unable to respond to stimuli or move.
