* ATP is a product of cellular respiration, which uses glucose as a reactant.

Here's why:

* Cellular respiration is a complex process that breaks down glucose (a sugar) in the presence of oxygen to release energy.

* ATP (adenosine triphosphate) is the energy currency of cells. It's produced during cellular respiration.

* Glucose is the primary reactant in cellular respiration. It's the fuel source that gets broken down to release energy.

So, while ATP is a product, it's not directly a product of glucose alone. It's a product of the entire process of cellular respiration, which uses glucose as a reactant.
