Question

multiple choice question
the liver converts what back to pyruvate?

lactate
acetic acid
glucose

Explanation:

In biochemistry (a subfield of Biology, Natural Science), the Cori cycle involves the liver converting lactate back to pyruvate (and then to glucose). Acetic acid is not converted to pyruvate by the liver in this context, and glucose is the product of gluconeogenesis from lactate, not the substrate to become pyruvate here. So the correct option is Lactate.

Answer:

A. Lactate
