Question

where does electron transport system occur in mitochondria? State the role of oxygen in ETC.

Answer 1

In mitochondria. Most eukaryotic cells have mitochondria, which produce ATP from products of the citric acid cycle, fatty acid oxidation, and amino acid oxidation. At the mitochondrialinner membrane, electrons from NADH and FADH2 pass through the electron transport chain tooxygen, which is reduced to water.
