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.
Electron Transport Chain - the high energy electrons trapped in NADH and FADH in glycolysis, pyruvate oxidation, and the Krebs cycle are used to produce ATP through chemiosmosis. O2 is the final acceptor of high energy electrons. In eukaryotesIn eukaryotes. glycolysis occurs in the cytoplasm, pyruvate oxidation, the Krebs cycle and the Electron
