Answer: Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP)
Explanation: This equation summarizes the overall process of cellular respiration, which involves the breakdown of glucose (a sugar) and the consumption of oxygen to produce carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate). This process occurs in the mitochondria of eukaryotic cells and in the cytoplasm of prokaryotic cells, and is essential for the survival and function of all living organisms.
