      The citric acid cycle occurs in the matrix of mitochondria. The cycle is sometimes called the Krebs cycle, named for Sir Hans Krebs, who described the fundamentals of the reactions in the 1930s. The cycle begins by the addition of a two-carbon acetyl group to a four-carbon molecule, forming a six-carbon citrate (citric acid) molecule.

      The Krebs Cycle Pyruvic acid is formed during glycolysis. If oxygen is present, the pyruvic acid moves into the Krebs cycle. In the Krebs cycle, pyruvic acid is changed into carbon dioxide.

      Cell Cycle. Name and describe what occurs during each step of the cell cycle. The cell cycle is the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells. The four main stages of the cell cycle are: Gap (G1), Synthesis (S), Gap 2 (G2) and Mitosis (M). Gap 1 – cells grow, carry out normal functions,

      Hence, we have a cycle. You may also have heard the Krebs cycle called the Citric Acid Cycle -- now the reason should be obvious! Notice the spelling has no apostrophe - Hans Krebs was the German-British scientist who, in the 1930's, contributed significantly to the understanding of this cycle.

      Respiration involves glycolysis, the Krebs cycle, and electron transport: an overview (pp. 160-161, FIGURE 9.6) Glycolysis and the Krebs cycle supply electrons (via NADH) to the transport chain, which drives oxidative phosphorylation. Glycolysis occurs in the cytosol, the Krebs cycle in the mitochondrial matrix.
