Final answer:
Cellular respiration requires oxygen and glucose to produce ATP, involving stages such as glycolysis, the Krebs cycle, and the electron transport chain.
Step-by-step explanation:
The components required for cellular respiration include oxygen and glucose as reactants. The stages of cellular respiration are glycolysis, the Krebs cycle, and the electron transport chain. Oxygen, required for the latter two stages, is the final electron acceptor, allowing glucose to be completely broken down into carbon dioxide and water. This process takes place primarily in the mitochondria within our cells and results in the production of ATP, the energy currency of cells. The role of the digestive, cardiovascular, and respiratory systems is critical in supplying glucose and oxygen for respiration and removing carbon dioxide as a waste product.
