Cellular respiration may be defined as the process that converts the biochemical energy of the nutrients that are stored is converted into the ATP molecule. ATP is the energy currency of the cell.
The glucose molecule is broken down into the ATP. this process of glycolysis occurs in the cytoplasm of the cell. The electron transport chain that present in mitochondria produces ATP. This process occurs in the presence of oxygen. Fermentation process do not occur in mitochondria.
