What is chemiosmosis, and how is it used to synthesize ATP? Use the following terms in your

explanation: inner mitochondria membrane, mitochondrial matrix, endergonic, exergonic, ADP, Pi,
and NADH/FADH2 What will be an ideal response?


In chemiosmosis, the exergonic flow of electrons (donated by NADH and FADH2) down the electron
transport chain is used to pump protons from the mitochondrial matrix across the inner mitochondrial
membrane. The resulting proton gradient is used to drive the endergonic reaction in which ADP reacts
with Pi to form ATP
