Cori Cycle -

  • The Cori cycle or glucose-lactate cycle is metabolic cooperation between the skeletal muscle working under low oxygen conditions and the liver.
  • This cycle can be summarized as follows:
  • the conversion of glucose to lactic acid, or lactate, by anaerobic glycolysis in skeletal muscle cells;
  • the diffusion of lactate from muscle cells into the bloodstream, by which it is transported to the liver;
  • the conversion of lactate to glucose by hepatic gluconeogenesis;
  • the diffusion of glucose from the hepatocytes into the bloodstream, by which it is transported back to the skeletal muscle cells, thereby closing the cycle
  • When the muscles recover, the oxygen consumption of the muscles exceeds. 
  • This extra consumption of oxygen is called oxygen debt.
     

-Hence, the correct option is d
