Almost certainly the ones on the left side of the arrow (or on the bottom of the equilibrium constant expression). However, since you neglected to supply "this chemical reaction", we can't give you a better answer than that.
C6H12O6 and O2
Wrong
its NaOH+H2
Reactants in an equation are the elements that are mixed together. The products are the end result of the reactants that are mixed together.
the reactants are the two or more elements or compounds that react to form the products
The reactants are at the left in a chemical reaction.
Reactants
The substances you have at the beginning of a chemical reaction are the reactants or the reagents.
Reactants are added into the equation to form the chemical reaction. Reactants are substances that are changed into products. Without these reactants, there would be no formula, resulting in no product.
The substances you have at the beginning of a chemical reaction are called the reactants.
A reactant or reactants enters into a chemical reaction to form product(s)

A reactant or reactants enters into a chemical reaction to form product(s)
The starting materials in a chemical reaction are called reactants.
A chemical that undergoes a chemical reaction is called a reactant. The chemicals that are produced by a chemical reaction are called the products. So in a chemical reaction, reactants turn into products.
In a chemical reaction reactants are transformed in products.
In a chemical reaction, the starting materials are called the reactants.
The reaction must change the chemical nature of reactants.
