Some kinds of frogs freeze solid during the winter and then thaw in the spring. As the freezing progresses, blood circulation stops. How would you expect cells not being served by the circulatory system to produce ATP during this time, and what by-product would you expect to build up in the cells?

fermentation and lactate

Explanation:

Substrate level phosphorylation as Glycolysis takes place. This is because this is a pathway of energy production which occurs without the presence of oxygen. (since circulation has stopped oxygen supply has seized).

Therefore the pyruvate produced as product of glycolysis will be converted directly to lactate in a single step reaction by Lactate dehydrogenase enzyme in lactic acid fermentation. With lactate produced as the waste product.
