Glucose + 2X -enzymes-> 2 Pyruvic acid + 4ATP. What substances is indicated by "X" in this equation?
Let us represent the chemical reaction
Now multiply the number of moles to the number of moles of each element
for example =
This is not true but helps in determining the missing reactant or missing product as in this problem.
The result would be
Now show the number of atoms of each element in each compound we know.
Add the no. of elements in the products and subtract it from the elements in reactants. it will give
so the remaining atoms would be
