ATP Production during Aerobic
Respiration by Oxidative Phosphorylation involving an Electron Transport System
NADH and FADH2 carry protons
(H+) and electrons (e-) to the electron transport chain
located in the membrane. The energy from the transfer of electrons along the
chain transports protons across the membrane and creates an electrochemical
gradient or proton motive force. At the end of the electron transport system,
protons, electrons, and oxygen molecules combine to form water.
As the accumulating protons follow the electrochemical gradient back across
the membrane through an ATP synthase complex, the movement of the protons (proton
motive force) provides energy for synthesizing ATP from ADP and phosphate.
