What is the final electron acceptor in lactic acid fermentation?

Understand the Problem

The question is asking about the final electron acceptor in the process of lactic acid fermentation, which is a metabolic process that converts glucose to lactic acid when oxygen is not present.

Answer

pyruvate

The final electron acceptor in lactic acid fermentation is pyruvate.

Answer for screen readers

The final electron acceptor in lactic acid fermentation is pyruvate.

More Information

In lactic acid fermentation, pyruvate plays a crucial role in recycling NADH to NAD+, enabling glycolysis to continue producing ATP in the absence of oxygen.

Tips

A common mistake is assuming oxygen is the final electron acceptor in all types of respiration. Oxygen is the final electron acceptor in aerobic respiration, but in lactic acid fermentation, pyruvate is the final electron acceptor.
