According to the science education site Purchon, aerobic respiration is the process by which your body creates energy in the presence of oxygen. The body uses oxygen to convert nutrients into energy for your cells to use. The process of aerobic respiration creates several end products--some are useful, and some are regarded as waste.
According to the Stars and Seas science website, one of the end products of aerobic respiration is carbon dioxide. For each molecule of glucose--a sugar that acts as your body's main source of energy--aerobic respiration produces six molecules of carbon dioxide. Carbon dioxide contains one atom of carbon and two atom of oxygen. This molecule is regarded as a waste product, and carbon dioxide is released every time you exhale.
As Ohio State University professor Stephen T. Abedon explains, another end product of aerobic respiration is water. Water is a compound with two hydrogen atoms and one oxygen atom. Each molecule of glucose used for aerobic respiration produces six molecules of water. Like the carbon dioxide, water created as a result of aerobic respiration is regarded as a waste product and is removed from the body via excretion.
The most significant output of the process of aerobic respiration is ATP, or adenosine triphosphate. Molecules of ATP store and transfer energy throughout your body. When your cells use ATP for energy, it is broken down into its components, according to science website Flatrock. This recycling of ATP components allows them to be used again for energy production. If the recycling process didn't occur, you'd have to eat massive amounts of food to provide enough energy for your body. Abedon says that in most cases, 36 molecules of ATP are produced by each molecule of glucose. However, he notes that special organisms called prokaryotes can create 38 molecules of ATP per glucose molecule.
