Cellular respiration occurs in the mitochondria of the cells. This organelle contains all the components required for cellular respiration. The enzymes involved in this pathway would be present here. Actually this orgnelle only contains the enzymes invovled in the last two parts of respiration the TCA cycle and oxidative phosphorylation. The enzymes invovled in the TCA cycle are free floating in the cytoplasm like matrix of the mitochondria whereas the enzymes involved in oxidative phosphorylation are bound on the folds of mitochondrial membrane called the cristae. However the first part of cellular respiration is glycolysis, the splitting og 6C glucose into two 3C molecules. This step uses enzymes that are found outside of the mitochondrion instead in the cytoplasm of the cell and so the net ATP gained from each NAD here is only 2 as energy is required to get it across the mitochondrial membrane.
