Function of the Electron Transport Chain in Cellular Respiration
Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production. The electrons transfer their energy to the proteins in the membrane providing the energy for hydrogen ions to be pumped across the inner mitochondrial membrane. Electron Transport Chain Oxidative Phosphorylation Teachmephysiology 1 The function of the electron transport chain is to pump protons in the mitochondrion inter-membrane thus building up a proton gradient. . In the process protons are pumped from the mitochondrial matrix to the intermembrane space and oxygen is reduced to form water. The main function of the electron transport chain is to generate an electrochemical gradient which drives the synthesis of ATP during cellular respiration and photosynthesis in mitochondria and chloroplasts respectively. During cellular respiration electrons from the glucose molecule are harvested by electron. ...
