Wood 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?A) fermentation and alcoholB) photosynthesis and O2C) aerobic respiration and CO2D) fermentation and lactate

Answer:

D) fermentation and lactate

Explanation:

At a time when the wood frogs' blood circulation stops, the wood frogs body is compromised with oxygen supply, so to get ATP, the wood frogs cells will have to start the fermentation process in place of the cellular respiration. Fermentation is a process of obtaining energy that occurs without the presence of oxygen gas, so it is an anaerobic energy production pathway.

In addition to ATP, the fermentation process will accumulate lactate as a result of all enzymatic reactions present in the process.
