Verified step by step guidance

Understand the role of the electron transport chain (ETC) in cellular respiration, which is to transfer electrons through a series of complexes to ultimately produce ATP.

Identify the main complexes of the electron transport chain: Complex I (NADH dehydrogenase), Complex II (Succinate dehydrogenase), Complex III (Cytochrome bc1 complex), and Complex IV (Cytochrome C oxidase).

Recognize that each of these complexes plays a specific role in the transfer of electrons and the pumping of protons across the mitochondrial membrane.

Note that ATP dephosphorylase is not a recognized component of the electron transport chain. Instead, ATP synthase is the enzyme responsible for synthesizing ATP, but it is not considered one of the main complexes of the ETC.

Conclude that ATP dephosphorylase is not a complex of the electron transport chain, as it does not participate in the electron transfer process within the ETC.
