This is an incomplete question, here is a complete question.

Reactants undergo chemical reaction to form products. This chemical equation represents one such reaction. The coefficient for one of the  reactants or products is incorrect. Which part of the chemical equation is incorrect?

Answer : The incorrect option is, The coefficient for one of the reactants or products is incorrect.

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

The given chemical reaction is,

This reaction is an unbalanced chemical reaction because in this reaction number of oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '13' put before the and we get the balanced chemical equation.

The balanced chemical reaction will be,

Hence, the incorrect option is, The coefficient for one of the reactants or products is incorrect.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
