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.
a) calvin cycle
b) substrate-level phosphorylation
c) fermentation
d) deamination
e) oxidative phosphorylation
