The mitochondrion is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is the main area of the cell which is responsible for cellular respiration and production of ATP in the cell.

A significant electron transport chain is found in the internal mitochondrial layer where it fills in as the site of oxidative phosphorylation through the activity of ATP synthase. It is likewise found in the thylakoid film of the chloroplast in photosynthetic eukaryotes.

The mitochondrion has an external membrane and an inward layer with folds (cisternae). The electron transport chain is a progression of transmembrane proteins found in the inward layer.

The electrons are moved between these proteins which is utilized to pump protons ( H + ) to the space between the inward and the external membrane. This makes a slope that is utilized to at long last produce.
