What does lactate clearance refer to?

What does lactate clearance refer to?

• A. Removal of lactate from blood via oxidation and conversion to glucose
• B. Increase in lactate production
• C. Lactate remains in bloodstream
• D. Lactate stored as fat

Answer: (A)

Lactate clearance is about how quickly lactate is removed from the blood, mainly by being oxidized for energy or converted back into glucose. Lactate produced in muscles during intense exercise is transported to tissues such as the liver and heart. In the liver, lactate can be converted to pyruvate and then to glucose (the Cori cycle), while the heart and skeletal muscles can oxidize lactate directly to fuel their metabolism. So, clearance describes removal from circulation, not its production, persistence, or storage as fat.
