Document Summary
Glycolysis occurs in almost all living organism, but it does not generate very much energy in the form of atp. The end product (pyruvate) still contains a good deal of chemical potential energy in its bonds. In the presence of oxygen, pyruvate can be further oxidized to release more energy, first to acetyl-coa and then even further in the series of reaction in the citric acid cycle. Pyruvate oxidation is a key step that links glycolysis to the citric acid cycle. Eukaryotes = first step that takes place in the mitochondria. The oxidation of pyruvate connects glycolysis to the citric acid cycle. End product of glycolysis = pyruvate [which can be transported into mitochondria] Mitochondria are rod-shaped organelles surrounded by a double membrane. Inner and outer mitochondrial membranes are not close to each other in all areas because the inner membrane has folds that project inwards. Intermembrane space = the space between inner and outer membrane.
