Step 1: Understand the process of aerobic cellular respiration. It consists of three main stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation. Each stage contributes to the production of ATP, carbon dioxide (CO\(_2\)), and water (H\(_2\)O).
Step 2: Recall that glycolysis occurs in the cytoplasm and breaks down one molecule of glucose (C\(_6\)H\(_{12}\)O\(_6\)) into two molecules of pyruvate, producing 2 ATP and 2 NADH. No CO\(_2\) is released during glycolysis.
Step 3: In the citric acid cycle, each pyruvate is converted into acetyl-CoA, which enters the cycle. For each glucose molecule, the cycle produces 6 CO\(_2\), 2 ATP, and multiple electron carriers (NADH and FADH\(_2\)).
Step 4: During oxidative phosphorylation, the electron carriers (NADH and FADH\(_2\)) generated in previous steps donate electrons to the electron transport chain. This process uses oxygen (O\(_2\)) as the final electron acceptor and produces water (H\(_2\)O) and approximately 26-28 ATP.
Step 5: Combine the net products from all stages: glycolysis, the citric acid cycle, and oxidative phosphorylation. The complete aerobic respiration of one glucose molecule generates 6 CO\(_2\), 6 H\(_2\)O, and approximately 30-32 ATP.
