cell. • Inside the mitochondria, the glucose molecule will be “burned”

with the oxygen. • ENZYMES help. • Rearranging into carbon dioxide, water, and ATP.• 6CO2 is carried away by the blood, to the lungs, to be exhaled. • DURING cellular respiration, the CHEMICAL ENERGY in glucose, is

transformed into the energy molecule ATP.• ATP will be used to do the work of the cell, like building DNA,

proteins, lipids, transporting vesicles, etc.
