DEFINITIONS:

$1.)$ The subcompartment formed between the inner and outer mitochondrial membranes.

$2.)$ The mitochondrial electron$-$transport chain, which generates the proton gradient across the inner mitochondrial membrane that powers ATP synthase, producing most of the cell's ATP.

$3.)$ Mechanism by which a pH gradient across a membrane is used to drive an energy$-$requiring process, such as ATP production or the rotation of bacterial flagella.

$4.)$ Process in bacteria and mitochondria in which ATP formation is driven by the transfer of electrons from food molecules to molecular oxygen, with the intermediate generation of a proton gradient across a membrane.

$5.)$ The result of a combined pH gradient and membrane potential.

$6.)$ A sievelike membrane surrounding mitochondria that is permeable to all molecules of $5000$ daltons or less.
