What is one of the reactants of cellular respiration?

One of the reactants of cellular respiration is glucose. Glucose is a simple sugar that is broken down through a series of chemical reactions to release energy that can be used by cells to perform various functions. Glucose is obtained from the food we eat and is transported into cells where it is converted into usable energy through the process of cellular respiration.

During cellular respiration, glucose is oxidized in the presence of oxygen to produce carbon dioxide, water, and ATP (adenosine triphosphate) molecules, which are the energy currency of the cell. This process occurs in the mitochondria, where glucose is broken down step by step in the presence of enzymes to release energy in the form of ATP.

Overall, glucose is a vital component in the cellular respiration process as it provides the necessary energy for cells to carry out their functions and maintain cellular processes. It is the primary source of energy for most living organisms and plays a crucial role in sustaining life.
