Qué es el ciclo de Cori
What is the Corey Cycle?
Overview of the Corey Cycle
- The Corey cycle involves a recycling process of lactate produced in muscles during high energy demand with insufficient oxygen.
- Lactate is generated when muscle cells ferment glucose due to low oxygen availability, leading to energy production through fermentation.
Lactate and Glucose Transformation
- Muscle glycogen reserves are hydrolyzed into glucose, which is then fermented to produce lactate.
- Accumulation of lactic acid can lead to muscle acidity, which negatively affects performance.
Role of the Liver in the Corey Cycle
- Lactate exits muscle cells into the bloodstream and travels to the liver for conversion back into glucose.
- The enzyme glucose 6-phosphatase in the liver allows for dephosphorylation of glucose, enabling it to exit the liver and return to muscles.
