Cellular repiration takes place in the mitochodrion. The 3 phases of cellular respiration are Glycolysis (Fermentation), Krebs Cycle, and Electron Transport. Glycolysis takes place in the cytoplasm.The Krebs cycle and electron transport takes place in the mitochondria. Aerobic respiration (requires oxygen) includes glycolysis, krebs cycle, and electron transort with end products of carbon and hydrogen and a net gain of 36 ATP.ellular repiration takes place in the mitochodrion.
