What is The Respiratory role in energy metabolism?

The respiratory role in energy metabolism

Aerobic respiration is a process that generates adenosine triphosphate (ATP), the energy currency of cells, by oxidizing organic molecules, such as glucose, in the presence of oxygen. The respiratory chain is a series of electron transfer reactions that occur in the inner membrane of mitochondria, and it is the final step of aerobic respiration.

During the respiratory chain, electrons are passed from NADH and FADH2 to oxygen through a series of protein complexes, called electron transport complexes. This process creates an electrochemical gradient across the inner mitochondrial membrane, which is used to drive the synthesis of ATP by oxidative phosphorylation.

The overall reaction of the respiratory chain is:

```

NADH + FADH2 + O2 → NAD+ + FAD + H2O + ATP

```
