一、閱讀下列文獻後，試作答 5 個問題。(50%)

The Cori Cycle: Lactate as a Fuel Source

During exercise some of the lactic acid that is produced by skeletal muscles is transported to the liver via the blood. Upon entry into the liver, lactate can be converted to glucose via gluconeogensis. This “new” glucose can be released into the blood and transported back to skeletal muscles to be used as an energy source during exercise. The cycle of

lactate-to-glucose between the muscle and liver is called the Cori cycle.
