Answer: Cellular Respiration
Explanation: Is the process in which the cells of living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. The overall chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (stored in ATP)
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals.
