검증된 단계별 안내1
Understand the role of the electron transport chain (ETC) in cellular respiration: The ETC is the final stage of cellular respiration, where electrons are transferred through a series of protein complexes located in the inner mitochondrial membrane.
Recognize the source of electrons: Electrons are initially stripped from glucose during glycolysis and the citric acid cycle, and are carried to the ETC by NADH and FADH2.
Identify the final electron acceptor: In the ETC, electrons are passed through a series of complexes and ultimately transferred to oxygen (O2), which is the final electron acceptor.
Understand the formation of water: When oxygen accepts electrons, it combines with protons (H+) to form water (H2O). This is a crucial step in the process as it helps maintain the proton gradient used to produce ATP.
Conclude the process: The electrons from glucose end up in water (H2O) as a result of their transfer through the electron transport chain and reduction of oxygen.
