Verified step by step guidance

Understand the context of fermentation: Fermentation is a metabolic process that occurs in the absence of oxygen, allowing cells to regenerate NAD+ from NADH, which is crucial for glycolysis to continue producing ATP.

Identify the role of NAD+ and NADH: During glycolysis, NAD+ is reduced to NADH. For glycolysis to continue, NADH must be oxidized back to NAD+, which is a key function of fermentation.

Recognize the types of fermentation: Both lactic acid fermentation and alcohol fermentation serve the purpose of oxidizing NADH to NAD+, allowing glycolysis to proceed by regenerating NAD+.

Differentiate between the options: The correct function of both types of fermentation is the oxidation of NADH to NAD+, not the reduction of NAD+ to NADH, reduction of FAD to FADH2, or hydrolysis of ATP to ADP.

Conclude the primary function: The primary function of both lactic acid fermentation and alcohol fermentation is to ensure the continuous supply of NAD+ by oxidizing NADH, which is essential for ATP production through glycolysis.
