During a sprint, skeletal muscle relies on anaerobic glycolysis.
What is the primary purpose of converting pyruvate to lactate in this context?
- To regenerate NAD^+ required for the continuation of glycolysis
- To produce additional ATP molecules directly from the reduction step
- To shuttle acetyl-CoA into the mitochondria via the carnitine shuttle
- To lower the pH of the muscle to enhance oxygen delivery via the Bohr effect
