During recovery from high‑intensity exercise, lactate is primarily removed by conversion to glucose in the liver via which cycle?

• A. Gluconeogenesis
• B. Lipid oxidation
• C. Cori cycle
• D. Glycogenolysis

Answer: (C)

During recovery from high‑intensity exercise, lactate produced in working muscles is taken up by the liver and converted back into glucose, which helps replenish energy stores. This lactate‑to‑glucose recycling between muscle and liver is known as the Cori cycle. While gluconeogenesis is the general process of making glucose from non‑carbohydrate sources, the cycle name that describes this lactate shuttle specifically is the Cori cycle. Lipid oxidation and glycogenolysis don’t describe this lactate‑to‑glucose pathway.
