Concept:Glycolysis breaks down one glucose molecule into two pyruvate molecules, producing a net gain of 2 ATP and 4H.Explanation:Glucose is C6H12O6.In glycolysis, it is split into two molecules of pyruvic acid, each C3H4O3.Therefore, the products include 2C3H4O3.The net ATP yield from glycolysis is 2 ATP, not 1 ADP or 2 ADP.So the correct summary is:C6H12O6→2C3H4O3+4H+2ATPAnswer:Option B.
