Final answer:
During cellular respiration, matter moves through the body in a series of chemical reactions, converting carbohydrates and oxygen into carbon dioxide and water. This process occurs in four phases and results in the production of ATP.
Step-by-step explanation:
During cellular respiration, matter moves through the body in a series of chemical reactions that convert carbohydrates and oxygen into carbon dioxide and water. This process takes place in four phases: glycolysis, pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation. In these phases, glucose is broken down and carbon atoms are released as carbon dioxide, while oxygen is used as the final electron acceptor. The water produced is transported out of the cell, while the energy released is stored in ATP molecules.
