What process is described here? A concentration gradient of H + ions is created in the periplasmic space by actively transporting the ions across the membrane using the energy liberated when carrier molecules are oxidized. When the H + ions pass through ATPase, enough energy is generated to add phosphate groups onto ADP molecules.

Explanation:

The process by which ATP is generated by utilizing the large amount of energy released during the transfer of electrons from NADH or FADH₂ to the O₂  through a series of electron carrier present in the mitochondrial membrane is called oxidative phosphorylation.

The process of electron transfer is accompanied by the pumping of protons across inner membrane of mitochondria, from the  mitochondrial matrix to intermembrane space establishing electrochemical proton gradient.

The ATP synthase complex present in the mitochondrial membrane allows the protons to move down the proton gradient  as a result enough energy is released to add a phosphate group to ADP and form ATP inside the mitochondrial matrix.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
