Final answer:
Fermentation is the process that allows glycolysis to continue producing ATP under anaerobic conditions in human cells.
Step-by-step explanation:
Under anaerobic (anoxic) conditions, the process that allows glycolysis to continue producing ATP in human cells is fermentation. In fermentation, pyruvate, which is produced by glycolysis, is converted into either lactic acid or ethyl alcohol, depending on the organism. This allows glycolysis to continue, oxidizing NADH back into NAD+ and generating a small amount of ATP.
