Which stage of aerobic respiration is represented by the equation C6H12O6 + 6O2 = 6CO2 + 6H2O?

The equation C6H12O6 + 6O2 = 6CO2 + 6H2O represents the overall process of cellular respiration, where glucose (C6H12O6) is broken down in the presence of oxygen (O2) to produce carbon dioxide (CO2) and water (H2O), ultimately releasing energy. This process occurs in multiple stages, one of which is the Krebs Cycle, also known as the citric acid cycle or tricarboxylic acid cycle (TCA cycle).

During the Krebs Cycle, which takes place in the mitochondria, acetyl-CoA derived from glucose (after glycolysis) is oxidized, resulting in the production of carbon dioxide and high-energy electron carriers (NADH and FADH2). The equation exemplifies the complete oxidation of glucose to carbon dioxide and water, highlighting that the Krebs Cycle is crucial for breaking down glucose and capturing its energy in the form of electron carriers that power the Electron Transport Chain, the final stage of aerobic respiration.

In contrast, glycolysis, occurring in the cytoplasm, involves the initial breakdown of glucose into pyruvate and does not produce carbon dioxide or water directly. The Electron Transport Chain is a subsequent step
