Question

What is the breakdown of sugars to make ATP in the absense of oxygen?

Answer 1

Isn't that anaerobic respiration? Where you end up with lactic acid that makes your muscles feel sore?

Answer 2

Glycolysis breaks down sugars without requiring any oxygen.  Furthermore, your body breaks down the products of glycolysis (2 pyruvate molecules) and turns it into lactic acid in the absense of oxygen in a process called lactic acid fermentation.

there are other kinds of fermentation in other species such as alcohol fermentation in bacteria.
