The mitochondria is responsible for respiration, but glycolysis occurs in the cytoplasm of the cell. The Krebs cycle and electron transport both occur in the mitochondria of t â¦ he cell. Cellular aerobic respiration occurs within the mitochondria. Cellular respiration occurs in the mitochondria of a cell.
Stage 2 Aerobic Respiration. During aerobic cellular respiration, the pyruvate produced during glycolysis enters a mitochondrion where it is converted to a two-carbon compound, making a reaction. A Carbon dioxide molecule, a NADH molecule, and a two-carbon acetyl group are produced because of this reaction.n anaerobic process is a process that uses metabolism without air, while an aerobic process is a process that uses metabolism with air. Synopsis of Cellular Respiration. In Cellular Respiration, energy in organic compounds, including glucose, is harnessed.
