What Are the Three End Products of Aerobic Respiration?

The three end products of aerobic respiration are carbon dioxide, water and energy in the form of adenosine triphosphate, or ATP, according to the BBC. Aerobic respiration is a chemical process where the body takes in food substances and converts it into energy that can be used by the body. Aerobic respiration requires one crucial molecule: oxygen.

The entire chemical conversion process happens entirely in the mitochondrial cells. Aerobic respiration involves four different processes: glycolysis, formation of the acetyl coenzyme A, which is an intermediate, the citric acid cycle and chemiosmosis paired with movement across the electron transport chain.

The main goal of aerobic respiration to produce energy that can be used by the body, and these processes are extremely effective. Aerobic respiration produces a net gain of 36 ATP molecules with 252 kcal stored as total free energy in the phosphate bonds. To do this, aerobic respiration will take in a molecule of glucose, six molecules of oxygen, six molecules of hydrogen dioxide, 38 molecules of adenosine diphosphate, or ADP, and 38 phosphorous molecules, and converts it to six carbon dioxide molecules, 12 hydrogen dioxide molecules, 38 ATP molecules and 420 kcal. The extra energy is stored in the extra phosphate bond found in ATP, which has three phosphorous molecules, rather than ADP, which only has two.
