Read this article to learn about:- 1. Mitochondria – Power House of Cell 2. Organisation of the Respiratory Chain 3. Transport of Substances Into and Out. Mitochondria – Power House of Cell: The mitochondrion has been termed the "Power House" of the cell due to the following reasons: 1. Most of the useful energy derived from oxidation within the tissues [...]
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 [...]
