This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Metabolism of carbohydrate, Subject name: Biochemistry
Inhibition of glycolysis by increased supply of O2 is 
Select and explain. 
A. Crabtree effect, B. Pasteur effect, C. Lewis effect, D. Warburg effect
B: Pasteur effect
Answer: B: Pasteur effect 
Explanation: uCrab Tree Effect - Increasing concentrations of glucose accelerates glycolysis (the breakdown of glucose) which results in the production of appreciable amounts of ATP through substrate level phosphorylation. uPasteur effect - Under aerobic conditions, glycolysis is inhibited. This inhibitory effect of oxygen on glycolysis.uWarburg Effect - Most cancer cells predominantly produce energy by a high rate of glycolysis followed by lactic acid fermentation in the cytosol, rather than by a comparatively low rate of glycolysis followed by oxidation of pyruvate in mitochondria as in most normal cells.Lehninger, Albe (2008).
