This would be as simple as how many went in and the net result, but my first 2 attempts were incorrect: (1,2,2,2 -->2,4,2) and (1,4,2,2 -->2,2,2) Please include a reason why knowing the # of Carbons in glucose and pyruvate is a hint.

Add coefficients to the following reaction summary to show the net results of glycolysis. You do not need to add the water and hydrogen ions necessary to balance the overall reaction.

glucose+ ADP+ Pi+ NAD⁺ --> Pyruvate+ ATP+ NADH

Hint: One way to approach this is to write down all reactants and products of each step of glycolysis, and then add up the reactions. Note that glucose contains six carbon atoms and pyruvate contains only three carbon atoms.
