Oxidative Phosphorylation

Oxidative phosphorylation is the final step in cellular respiration. It occurs in the mitochondria. It is linked to a process known as electron transport chain. The electron transport system is located in the inner mitochondrial membrane. The electrons are transferred from one member of the transport chain to another through a series of redox reactions.

Oxidative Phosphorylation Steps:

The major steps of oxidative phosphorylation in mitochondria include:

  1. Delivery of Electrons by NADH and FADH2
  2. Electron Transport and Proton Pumping
  3. Splitting of Oxygen to form Water
  4. ATP Synthesis
