Localization of respiratory processes in the mitochondrion

Description
a. A mitochondrion from a pancreatic cell.

b. Overview of oxidative phosphorylation:

Reduced electron carriers, produced by cytosolic dehydrogenases and mitochondrial oxidative pathways, become reoxidized by enzyme complexes bound in the inner membrane.

These complexes actively pump protons outward, creating an energy gradient whose discharge through complex V drives ATP synthesis.
