Which of the following is NOT a process of cellular respiration?

The Cori Cycle is primarily a metabolic pathway involved in the conversion of lactate produced by anaerobic glycolysis in muscles back into glucose in the liver, which is then used for energy. While it plays an important role in energy metabolism, it is not a direct part of cellular respiration, which fundamentally consists of glycolysis, the Krebs cycle, and oxidative phosphorylation.

In contrast, glycolysis breaks down glucose into pyruvate, the Krebs cycle further processes these products to produce electron carriers, and oxidative phosphorylation generates ATP through the electron transport chain. Thus, the Cori Cycle, while related to energy metabolism, does not directly contribute to the phases of cellular respiration that are essential for ATP production in aerobic conditions.
