Oxidative phosphorylation Of course,The primary purpose of mitochondria is to phosphorylate ADP.
The energy needed to do that is stored as a gradient of protons.
Presumably,if a proton were allowed to come back into the matrix there would be a release of energy.
How can that energy be captured and exploited ?
Embedded in the inner membrane among the structures of the electron transport system are structures called the ATP synthase complex.
The complex consists of a proton channel and catalytic sites for the synthesis of ATP from ADP and phosphate.
When ADP and phosphate are available,they bind the catalytic sites on the ATP synthase.
When this happens,the channel opens,and protons can come whooshing back in.
The energy released is used to couple the phosohate to ADP,to make ATP.
