it is the main source of energy in Aerobic metabolism

what is the process of adding phosphate to ADP called?

Phosphorylation

What happens during oxidative phosphorylation?

There is the production of ATP using transfer of electrons from energy

How is energy captured in oxidative Phosphorylation?
