Final answer:
During cellular respiration, oxygen and glucose are the reactants that are converted into carbon dioxide, water, and ATP. Cellular respiration and photosynthesis are interconnected processes that form a cycle, with glucose produced in photosynthesis being used in cellular respiration. The main function of cellular respiration is to convert the energy in food into ATP.
Step-by-step explanation:
The reactants of cellular respiration are oxygen and glucose, which enter the body through breathing and eating, respectively. On the other hand, the products of cellular respiration are carbon dioxide, water, and ATP. Carbon dioxide is transported out of the mitochondria and to the lungs to be exhaled, while ATP is the energy molecule produced in the process.
Cellular respiration and photosynthesis can be seen as a cycle, as one produces the reactants of the other. Both processes use electron transport chains to capture energy.
Glucose, which is produced during photosynthesis, is used in cellular respiration to generate ATP. In the presence of oxygen, glucose is converted to carbon dioxide and water, releasing energy. Without oxygen, ATP production would significantly decrease.
Overall, cellular respiration is the process through which the energy stored in food is converted into ATP, with glucose and oxygen as reactants and carbon dioxide, water, and ATP as the products.
