Biology Word Search Worksheet on Cori Cycle

Sourav Bio

The Cori Cycle, also known as the Lactic Acid Cycle, is a metabolic pathway that involves the transport of lactate and glucose between the muscles and the liver. It was named after Carl Ferdinand Cori and Gerty Cori, who were awarded the Nobel Prize in Physiology or Medicine in 1947 for their discovery of this cycle. Here’s how the Cori Cycle works:

  1. Glycolysis in Muscles: During intense physical activity, the muscles produce energy rapidly through a process called glycolysis. In the absence of sufficient oxygen (anaerobic conditions), the end product of glycolysis is lactate (or lactic acid).
  2. Transport to the Liver: The lactate produced in the muscles is then transported to the liver via the bloodstream.
  3. Conversion to Glucose: Once in the liver, lactate is converted back into glucose through a series of reactions called gluconeogenesis.
  4. Return to Muscles: The newly formed glucose is then released into the bloodstream, transported back to the muscles, and stored as glycogen or used for energy.
  5. Reutilization: When the muscles require energy, the stored glycogen is broken down into glucose, which can then enter the glycolytic pathway, and the cycle continues.

The Cori Cycle is crucial because it helps to regenerate glucose from lactate, which allows muscles to continue working under anaerobic conditions for a short period. However, it’s worth noting that the Cori Cycle is not energy-efficient. The energy required to convert lactate back into glucose in the liver is greater than the energy produced by the muscles from glycolysis. This energy inefficiency is why sustained high-intensity activity can’t rely solely on anaerobic metabolism and the Cori Cycle.
