Anaerobic metabolism due to decreased oxygen creates which acids that contribute to metabolic acidosis?

Explanation:
When oxygen is scarce, cells rely on anaerobic glycolysis. Pyruvate from glycolysis is converted to lactate to regenerate NAD+, allowing glycolysis to continue. This lactate production releases hydrogen ions, lowering pH and causing metabolic acidosis. Pyruvic acid is the immediate substrate in this pathway, and lactate is the main acid that contributes to the acidosis, so including both lactic and pyruvic acids best reflects what happens in this situation. The other acids listed are not the primary products of human anaerobic metabolism in this context.
