How is cellular respiration carried out in the human body?

All livings need a continuous supply of energy, as energy is used in a wide range of process including active transport and protein synthesis with happen in the human body.  Most of these processes need energy in the form of Adenosine Triphosphate (ATP), which is a chemical substance that can disperse to any part of the cell and release energy. Every cell produces its own ATP by a process of cell respiration. Cell respiration is defined as “controlled release of energy in the form of ATP, from organic compounds in cells” (1).  Cell respiration can be either aerobic (using oxygen) or anaerobic (without the use of oxygen).  Glucose is often the organic compound used in cellular respiration.  The chemical reactions that take place in the cytoplasm break down the glucose into a simpler organic compound called pyruvate, in these reactions a very small amount of ATP is produced using energy released from glucose.

Cellular respiration is the process in which energy in organic compounds including glucose are broken down, therefore are three main stages of cellular respiration, the first stage is where glucose is broken down in the cytoplasm through glycolysis and is then converted into pyruvate , this produces a small amount of Adenosine Triphosphate (ATP) and NADH.  This process can either be done aerobically (with oxygen) or anaerobically (without oxygen).  In an aerobic process of cellular respiration the stage two is when pyruvate and NADH are both used to make ATP, however when this is done anaerobically the pyruvate is converted into either ethanol and carbon dioxide or lactate this is done through fermentation.

        Cellular Respiration can be seen more simply in the chemical equation:

The equation in words:

Glucose is needed to start glycolysis, and the oxygen is needed for the glycolysis to move through the Krebs cycle or go though fermentation.  Through the use of enzymes carbon dioxide is produced and released from the six carbon compound in the Krebs cycle.  Water is also produced in the electron transport chain when hydrogen ions and oxygen as well as electrons combine.  Lastly ATP is created in the electron transport chain through a channel of protein.
