The following points highlight the five main enzymes involved in oxidative process. The enzymes are: 1. Oxidases 2. Aerobic Dehydrogenases 3. Anaerobic Dehydrogenases 4. Hydro-peroxidases 5. Oxygenases. Oxidative Processes: Enzyme # 1. Oxidases: (a) Enzymes that catalyse the removal of hydrogen from a substrate but use only oxygen as a hydrogen acceptor to form water as a reaction product (with [...]
In this article we will discuss about the Chemiosmotic Theory of Mitochondrial Membrane. It is explained that the primary event in oxidative phosphorylation is the translocation of protons (H+) to the exterior of a coupling membrane driven by oxidation in the respiratory chain. The membrane is impermeable to protons which accumulate outside the membrane creating an electrochemical potential difference across [...]
In this article we will discuss about the Energy Capture in Respiratory Chain in Mitochondria. 1. When substrates are oxidized through an NAD-linked dehydrogenase, 3 mol inorganic phosphate are incorporated into 3 mol of ADP to form 3 mol of ATP per half mol of O2 (1/2 O2) consumed, i.e. the P; O ratio = 3. 2. When a substrate [...]
