WebThere are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs. The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions. WebDec 5, 2024 · The Krebs Cycle occurs in the mitochondria, which is also known as the power house of the cell. After pyruvate arrives from the cytoplasm, each molecule is completely broken down from a three-carbon sugar into a two-carbon fragment. The resulting molecule is attached to a co-enzyme, which starts the Krebs Cycle.
