an octahedron: basically two square based pyramids with their bases stuck together.
Most eukaryotic cells have mitochondria, which produce ATP from products of the citric acid cycle, fatty acid oxidation, and amino acid oxidation. At the mitochondrial inner membrane, electrons from NADH and succinate pass through the electron transport chain to oxygen, which is reduced to water.
The electron transport chain is the path in which the electrons travel during cellular respiration. The electron transport system is the set of proteins and other cellular câ¦omponents that are involved in the electron transport chain. For example, the both aerobic and anaerobic organisms, there are different electron transport systems and this influences the path electrons take.
