Verified step by step guidance

Understand the role of fermentation in cellular respiration. Fermentation is an anaerobic process that allows cells to continue producing ATP when oxygen is scarce.

Recognize that glycolysis is the first step in cellular respiration, where glucose is broken down into pyruvate, producing ATP and NADH in the process.

Identify the need for NAD+ in glycolysis. NAD+ is a coenzyme that accepts electrons during glycolysis, becoming NADH. Without recycling NADH back to NAD+, glycolysis would halt.

Learn how fermentation recycles NADH to NAD+. In the absence of oxygen, fermentation pathways convert NADH back to NAD+, allowing glycolysis to continue producing ATP.

Differentiate between the options given. Fermentation does not use NADH as a terminal electron acceptor, nor does it synthesize ATP via ATP synthase. Its primary function is to recycle NADH to NAD+.
