Reactant
product
Glucose is a reactant in cellular respiration. Carbon dioxide is a product of cellular respiration.
The limiting reactant is that reactant in a chemical reaction that will be used up first. Put another way, it is the reactant that is in the smallest supply. The way it controls the amount of product formed is that once it is used up, no more product can be formed, so the amount of product formed ultimately depends on the amount of the limiting reactant.

Glucose is a reactant in cellular respiration. Carbon dioxide is a product of cellular respiration.
Sugar can be both a reactant and a product, depending on the chemical reaction. For example, in the process of photosynthesis, sugar (glucose) is produced as a product. However, in the process of fermentation, sugar is a reactant that is broken down to produce other products like ethanol and carbon dioxide.
Glucose is a product of photosynthesis and a reactant in cellular respiration.
Copper can be both a product and a reactant in chemical reactions. It can act as a reactant when it undergoes oxidation reactions, and as a product when it is the desired outcome of a reaction involving copper-containing compounds.
Chlorine can be both a reactant and a product, depending on the chemical reaction it is involved in. It can react with other substances to form new compounds as a reactant, or it can be generated as a product from certain reactions.
For copper, it is an element. It could be both reactant and product. While purifying copper will be the product. But copper would be the reactant in case of preparing hydrogen or copper sulphate salts.
Sodium acetate can be either a reactant or a product in a chemical reaction, depending on the specific reaction conditions. It can act as a reactant when combining with other substances to form new compounds, or as a product when it is formed as a result of a reaction.
