This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Carbohydrates, Subject name: Biochemistry
Cancer cells derive nutrition from: 
Select and explain. 
A. Anaerobic glycolysis, B. Oxidative phosphorylation, C. Increase in mitochondria, D. Aerobic Glycolysis
D: Aerobic Glycolysis
Answer: D: Aerobic Glycolysis 
Explanation: Ans. D. Aerobic glycolysis(Ref: Harper 31/e page 695) (Harrison 19/e page 102 e-13)Many cancer cells use aerobic glycolysis (Warburg effect) to metabolize glucose leading to increased lactic acid production, where as normal cells use oxidative phosphorylation in mitochondria under aerobic conditions, a much more efficient process.
