What is the net yield of ATP produced by the anaerobic fermentation of one molecule of galactose to two molecules of lactate in myocytes  (A) 2  (B) 3   (C) 4  (D)  6  (E) None of the answers is correct

The answer is A.

I am confused by the question itself because one molecule of galactose goes into glycolysis after a couple steps to form one molecule of glucose, how can it generate two molecules of lactate, instead of just one?
Thank you.

By counting carbons it should yield two.
