How is ATP produced in the ETC


How is ATP produced in the ETC

Step 1

ATP (adenosine triphosphate) is an organic molecule that is responsible for providing energy to various biological processes and functions, such as, nerve impulse propagation, muscle contraction, and chemical synthesis. ATP is found in all living beings and is commonly termed as the “molecular unit of currency”. When it is consumed in any biological process, then it gets hydrolyzed into ADP and inorganic phosphate or AMP and pyrophosphate.

Step 2

The electron transport chain is a series of electron transporters located in the inner membrane of mitochondria. This ETC is the major source of ATP production in the cell. In the electron transport chain, electrons pass from one protein complex to another protein complex, until they are accepted by the oxygen molecule. During this process, protons pump out of the mitochondria to the inte...
