Cellular respiration is the process by which glucose is broken down to carbon dioxide and water in the cell.
Cellular respiration refers to the process in which glucose is broken down to produce energy. The reaction of cellular respiration is; C6H12O6 -----> 6H20 + 6CO2. This process occurs in the mitochondria of the cell which is within the cytoplasm. In times of oxygen deficit, lactate or ethanol may be produced by the process.
