Respiration is the release of energy from glucose or another organic chemical. The chemical energy in glucose can be used to provide the energy required for growth, repair and movement.
Involves the exchange of oxygen and carbon dioxide at the respiratory surface. Involves the breakdown of complex organic such as glucose into simpler molecules with release Of energy. (ATP) RESPIRATION EXTERNAL CELLULAR
The Krebs cycle affects all types of life and as such, the metabolic pathway within the cells, which chemically converts carbohydrates, fats and proteins into carbon dioxide and converts water into serviceable energy.
The Krebs cycle concerns the second of three major stages every living cell must undergo in order to produce energy, which it needs in order to survive.
At the end of the system, the hydrogen ions and electrons recombine and are then used to reduce oxygen to form water.
The formation of ATP through the oxidation of hydrogen atoms is called Oxidative Phosphorylation:
2 molecules of ATP are produced from each FADH2 molecule.
3 molecules of ATP are produced from each NADH + H+ molecule.
