Cellular respiration is defined as an enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka‚ Diaz and Villa‚ 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates‚ such as glucose‚ is a fundamental part of cellular respiration (Mader‚ 2009). As a catabolic process‚ it may or may not require the presence of oxygen. The process that requires oxygen is called aerobic
