Final answer:
The statement about the Cori cycle is true; it is the process where lactate from muscles is converted to glucose in the liver through gluconeogenesis and then sent back to muscles, aiding in blood sugar regulation and lactic acid elimination.
Step-by-step explanation:
The statement that the Cori cycle converts lactate produced in muscle into glucose through gluconeogenesis in the liver is true. The process begins when glucose is broken down in the muscles through glycolysis, producing pyruvate that is subsequently converted into lactate under anaerobic conditions.
This lactate is then transported to the liver where it is utilized to synthesize new glucose molecules via gluconeogenesis. This newly-formed glucose can then be transported back to the muscles to be reused as a source of energy, effectively completing the cycle. This cycle is crucial for maintaining energy balance during strenuous exercise or fasting since it helps in the regulation of blood sugar levels and the elimination of lactic acid from muscle tissue.
