Verified step by step guidance1
Understand the process of aerobic respiration, which involves glycolysis, the citric acid cycle, and the electron transport chain.
Recognize that the electron transport chain is the final stage of aerobic respiration, where electrons are transferred through a series of proteins embedded in the inner mitochondrial membrane.
Identify the role of electron carriers such as NADH and FADH2, which donate electrons to the electron transport chain.
Learn that as electrons move through the chain, they release energy used to pump protons across the membrane, creating a proton gradient.
Know that oxygen acts as the final electron acceptor, combining with electrons and protons to form water, completing the process of aerobic respiration.
