3.) Tumors & Lactate. When tumor cells spread to regions of the body with low oxygen levels, the tumor cells generate adenosine triphosphate (ATP) from breaking down glucose into lactate. This is called the Warburg theory of cancer. How do DNA mutations that are present in these tumor cells enable them to thrive in low and high oxygen microenvironments? Write down your hypothesis.

Glycol- ysis is common to fermentation and cellular respiration. The end prod- uct of glycolysis pyruvate, represents a fork in the catabolic pathways of glucose oxidation. In a facultative anaerobe or a muscle cell, which are capable of both aerobic cellular respiration and fermentation, pyru- vate is committed to one of those two pathways, usually depending on whether or…
