Detailed explanation-1: -Cellular respiration takes place in the cytoplasm and mitochondria of each cell of the body. Glycolysis occurs inside the cytoplasm, while the TCA cycle occurs inside the matrix of the mitochondria.
Detailed explanation-2: -Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration.
Detailed explanation-3: -The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).
Detailed explanation-4: -Stages of Cellular Respiration Glycolysis occurs in the cytosol of the cell and does not require oxygen, whereas the Krebs cycle and electron transport occur in the mitochondria and do require oxygen.
