Verified step by step guidance

Understand the role of NADH in cellular respiration: NADH is primarily involved in transporting electrons to the electron transport chain, which is crucial for the production of ATP through oxidative phosphorylation.

Review the process of glycolysis: During glycolysis, glucose is broken down into pyruvate, and NAD+ is reduced to form NADH. However, ATP is produced directly through substrate-level phosphorylation, not by NADH.

Examine the electron transport chain: NADH donates electrons to the electron transport chain, which helps establish a proton gradient used to produce ATP via oxidative phosphorylation.

Consider the role of NADH as a reducing agent: In metabolic reactions, NADH acts as a reducing agent by donating electrons, which is essential for various biochemical processes.

Identify the statement that does not align with NADH's roles: Since NADH does not directly produce ATP in glycolysis, this is the correct answer to the question.
