A
It occurs in the absence of oxygen
B
It results in a variety of byproducts
C
It regenerates NAD+
D
It uses ATP
Verified step by step guidance
1
Understand the process of fermentation: Fermentation is a metabolic process that occurs in the absence of oxygen (anaerobic conditions) and allows cells to generate energy.
Identify the main purpose of fermentation: The primary goal of fermentation is to regenerate NAD+ from NADH, which is crucial for glycolysis to continue producing ATP in the absence of oxygen.
Recognize the byproducts of fermentation: Depending on the type of fermentation (e.g., lactic acid fermentation or alcoholic fermentation), various byproducts such as lactic acid, ethanol, and carbon dioxide are produced.
Clarify the role of ATP in fermentation: Fermentation itself does not use ATP; rather, it allows glycolysis to continue, which produces a small amount of ATP.
Determine the statement that does not fit: Since fermentation does not directly use ATP, the statement 'It uses ATP' is not associated with fermentation.
