Question
Chapter 16, Problem 14P
Interpretation Introduction
Interpretation:
The fate of glucose-6-phosphate formed by hexokinase in glycolysis should be determined.
Concept introduction:
Glycolysis is the conversion of one molecule of glucose into two molecules of pyruvate. During this process, two molecules of ATP and two molecules of NADH are produced. Glycolysis is divided into two phases, the preparatory phase, and payoff phase. In the preparatory phase, ATP is consumed, while in the payoff phase ATP is produced.

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.
