Think about the average yield of ATP in eukaryotic cells. Is it stable or variable? The yield is variable because the demand for the products is variable. ATP isn't always required, so there are time when the cell takes break to reserve sugars. The yield is steady because the enzymes and complexes used in the process are completely dedicated to cellular respiration, therefore, the process runs smoothly from start to finish every time. There are not often hang ups, fits, and starts as the products progress. The yield is variable because the enzymes and complexes used in the process are not completely dedicated to cellular respiration, therefore, the process doesn't run smoothly from start to finish every time. There are often hang ups, fits, and starts as the products progress.

Many cancer cells preferentially perform aerobic glycolysis Proliferative tissue 5. Tumor without relying on oxidative phosphorylation to generate energy, a pro- cess known as the "Warburg effect". While less efficient at generating ATP, it has been proposed that the Warburg effect promotes prolifera- tion by generating an abundance of glycolytic intermediates that serve as precursors for other anabolic processes to generate biomass. One consequence of the Warburg effect is that cancer cells that are not bathed in a constant source of fresh glucose – such as cells in a solid tumor that are far from any capillaries (e.g., non-small cell (NSC) lung cancer) – often run out of glucose and activate gluconeogenesis. In this situation, the lactate generated by anerobic glycolysis is converted back to pyruvate to begin gluconeogenesis. or +/-02 Glucose Pyruvate 5% 85% Lactate CO2 (a) matic steps.
