Where is the ETC located?

The Electron Transport Chain is in the mitochondrial membrane. Prokaryotes do not contain organelles such as mitochondria, but they do have ETC. Most living cells generate energy from nutrients after cellular respiration that entails the ability of oxygen to release energy.

The electron transport chain, ETC, is the third and final step of this process. The other is glycolysis and the citric acid cycle. The ETC is the third and final cellular respiration stage from an energy perspective because it creates the most ATP.

In a sequence of redox reactions, energy is used to connect a third phosphate group to adenosine diphosphate to produce ATP with three phosphate groups. When a cell requires energy, it halts the third phosphate group bend and uses the resulting energy.

The location of the ETC or Electron Transport Chain is in the mitochondria. In the inner membrane of the mitochondria, there are about five protein complexes that form this chain. The Electron Transport Chain helps the body cells in the production of ATP.

The ETC is able to generate the energy needed by the cells when its five protein complexes get electrons from the two main electron carriers (NADH and FADH2). The electrons gotten by the five protein complexes of the ETC creates a form of energy that forces hydrogen ions into the intermembrane space of the cell.

The activities of the hydrogen ions lead to the production of ATP from ADP. The mitochondria don't produce large amounts of ATP but instead ensures that the concentration of ADP is high so that the cell can get enough ATP. The reason is that when ATP is produced in large amounts, it will reduce the concentration of ADP.

ETC is also known as Electric Transport Chain. The electric transport chain is known to be a series of proteins and organic molecules that can be found in the mitochondria. Take note that this can be found in the inner membrane of the mitochondria.

The main goal of the ETC is to make sure that it will produce different types of high−energy molecule adenosine triphosphate, also known as ATP, to ensure that biochemical reactions can be done properly.

There are different hydrogen ions and protons that will be placed in the intermembrane space. The different precursors of the ATP, adenosine diphosphate, and inorganic phosphate will then be placed in the mitochondrial matrix.
