Oxidative Phosphorylation
The third part of Cellular Respiration is Oxidative Phosphorylation. In this part, the electron transport chain takes the electrons from the broken down products of the other two parts and transfers these electrons between molecules. Once the electrons reach the end of the chain, they are combined with oxygen and hydrogen ions to form water, releasing water as a product. Energy created as the electrons move down the chain results in the production of ATP. However, this ATP is created by redox reactions transfering the electrons down the chain, making this mode of "ATP Synthesis" called Oxidative Phosphorylation.
