Verified step by step guidance1
Understand the concept of the electron transport chain (ETC) in cellular respiration, which is a series of protein complexes located in the inner mitochondrial membrane.
Recognize that the ETC is responsible for transferring electrons from electron donors like NADH and FADH2 to electron acceptors through a series of redox reactions.
Identify that the final electron acceptor in the electron transport chain is a crucial component, as it allows the chain to continue functioning by accepting electrons.
Recall that oxygen (O₂) is the final electron acceptor in the electron transport chain. It combines with electrons and protons to form water (H₂O), which is essential for the continuation of the process.
Understand that without oxygen as the final electron acceptor, the electron transport chain would halt, leading to a lack of ATP production through oxidative phosphorylation.
