Verified step by step guidance1
Understand the context of the electron transport chain (ETC) in cellular respiration, where electrons are transferred through a series of protein complexes to ultimately produce ATP.
Identify the role of NADH in cellular respiration. NADH is a carrier molecule that stores energy in the form of high-energy electrons.
Recognize that NADH is produced during glycolysis and the Krebs cycle, and it donates electrons to the electron transport chain.
Consider the role of oxygen in the electron transport chain. Oxygen acts as the final electron acceptor, not a source of electrons.
Conclude that NADH is the primary source of electrons in the electron transport chain, as it donates electrons to the chain, facilitating the production of ATP.
