Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
While most aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm.
Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.
the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
