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.

cramming before a final is bad because it makes a student's stress level higher. students who embrace cramming to get through a final exam week find themselves struggling to perform consistently, once the brain adjusts to prolonged sleep deprivation.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
