Question

the liver converts what back to pyruvate?
o glucose
o lactate
o acetic acid

Explanation:

During the Cori - cycle, lactate produced in muscles is transported to the liver. In the liver, lactate is converted back to pyruvate by the enzyme lactate dehydrogenase. Glucose is not directly converted back to pyruvate in this context and acetic acid is not involved in this particular conversion pathway in the liver.

Answer:

Lactate
