How many molecules of ATP are formed per molecule of oxidation of glucose?(a) 12(b) 24(c) 36(d) 48I had been asked this question in examination.My question is from Metabolism in chapter Bioenergetics, Enzymes, Metabolism, Genes, Chromosomes and Genomes of Cell Biology

Answer»

Correct CHOICE is (C) 36

The EXPLANATION: In one cycle of glycolysis, 6 ATP is obtained. Each MOLECULE of glucose gives 2 pyruvate which corresponds to 6 ATP. There is also formation of 2 acetyl-CoA molecules which is about 24 ATP. Thus each molecule of Glucose give 36 ATP. ( Note that about 34 ATP molecules are consumed in glycolysis thus the net yield is 2 ATP).
