Cell Respiration - 12 Aerobic (Cellular) Respiration Summary The complete aerobic respiration of glucose requires the following: Glycolysis Pyruvate Oxidation and the Krebs cycle Electron transport phosphorylation Oxygen, the final electron acceptor in the electron transport system, combines with Hydrogen to form water. Carbon Dioxide (CO 2 ) is released during aerobic respiration. 36 ATP can be produced for each glucose molecule. The Krebs cycle and electron transport occur in the mitochondria. Glycolysis occurs in the cytosol. All steps are catalyzed by enzymes Generating Heat From Cell Respiration - Thermogenesis There are times when generating heat rather than ATP is desired.

Unformatted text preview: For example, organisms, such as bats, need to increase body temperature rapidly when they wake. There are special proteins, called uncoupling proteins, that separate the H + proton flow in electron transport from the ATP synthase pump, so that heat is produced instead of ATP. Plants also have uncoupling proteins for heat generation. Arum lilies attract carrion beetles and flies for pollination by exuding odors that smell like carrion. Skunk cabbage elevates its body temperature as much as 10 - 12 C above ambient air temperature for flowering. Plants emerge through snow in the spring use thermogenesis, too. Arum Thermogenesis...
