Verified step by step guidance1
Understand the process of aerobic cellular respiration, which involves the breakdown of glucose in the presence of oxygen to produce energy, carbon dioxide, and water.
Identify the stages of aerobic respiration: glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain (ETC).
Focus on the electron transport chain, where oxygen plays a crucial role as the final electron acceptor.
Recognize that during the electron transport chain, electrons are transferred through a series of proteins, and oxygen gas (O2) accepts these electrons at the end of the chain.
Learn that when oxygen accepts electrons, it combines with protons (H+) to form water (H2O), making oxygen gas (O2) the source of the oxygen atom in the water produced during aerobic respiration.
