Question: 1 / 2700

Which of the following is NOT a characteristic of fermentation?

It produces energy

It requires glucose

It is anaerobic

It requires oxygen

Fermentation is a metabolic process that occurs in the absence of oxygen, making it anaerobic. One of its primary functions is to produce energy, especially when oxygen is scarce. It typically involves the breakdown of glucose or other carbohydrates, yielding byproducts like alcohol or lactic acid. The need for glucose is a characteristic, as it serves as a substrate for the process. However, oxygen is not required for fermentation; rather, its absence is what defines this type of energy production. Thus, stating that fermentation requires oxygen is incorrect, as it contradicts the fundamental nature of the process.
