During strenuous exercise,human muscle cells can become oxygen-deprived.When this occurs,muscle cells perform anaerobic fermentation,which results in the production of lactate from pyruvate.What happens to the lactate produced in muscle cells? A)It is reduced and converted back to pyruvate in muscle cells. B)It is oxidized to CO₂ and water. C)It is taken to the liver and converted back to pyruvate. D)It is converted to alcohol.

The lactate produced in muscle cells is transported to the liver, where it is converted back to pyruvate in a process called the Cori cycle. The pyruvate can then enter the citric acid cycle and be oxidized to produce ATP.
