WebEnergy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation. The key steps of this process, shown in simplified form in the diagram above, include: Web1 aug. 2014 · Reactive Oxygen species (ROS) In the mitochondrial respiratory chain, Complex IV (cytochromeoxidase) retains all partially reduced intermediates until full reduction is achieved. Other redoxcentres in the electron transport chain, however, may leak electrons to oxygen, partially reducing this molecule to superoxide anion (O2−•).
