Chemiosmosis involves
the movement of electrons across the cell membrane
the movement of hydrogen atoms across a mitochondrial membrane
the movement of hydrogen ions across a mitochondrial membrane
the movement of glucose through the cell membrane

the movement of hydrogen ions across a mitochondrial membrane is a correct answer.

Explanation:

Chemiosmosis involves the movement of hydrogen ions across a mitochondrial membrane.Chemiosmosis is the hydrogen movement ions across the semipermeable membrane from the area of high concentration to lower concentration.Chemiosmosis function is to produce ATP through cellular respiration in the mitochondria this process is called oxidative phosphorylation and the ATP produce during the Chemiosmosis provide energy to the living cells.

The correct answer is b
