WebGlycolysis occurs in the cytosol of the cell and does not require oxygen, whereas the Krebs cycle and electron transport occur in the mitochondriaand do require oxygen. Cellular respiration takes place in the stages shown here. The process begins with a molecule of glucose, which has six carbon atoms. What happens to each of these atoms of carbon? WebStep 1. In the first step of the citric acid cycle, acetyl \text {CoA} CoA joins with a four-carbon molecule, oxaloacetate, releasing the \text {CoA} CoA group and forming a six-carbon molecule called citrate. Step 2. In the second step, citrate is converted into its … In eukaryotes, this step takes place in the matrix, the innermost compartment of … Glycolysis, the preparatory stage and the Krebs or citric acid cycle.
