The inner mitochondrial membrane.


The mitochondrion has an outer membrane and an inner membrane with folds (cisternae). The electron transport chain is a series of transmembrane proteins found in the inner membrane.

The electrons are shuttled between these proteins which is used to pump protons (#H^+#) to the space between the inner and the outer membrane. This creates a gradient that is used to finally produce ATP = energy ready to go!
