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 [...]
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 [...]
Quick Notes on Mitochondria:- 1. Introduction to Mitochondria in Cell 2. Origin of Mitochondria in Cell 3. Structure 4. Function. Introduction to Mitochondria in Cell: Mitochondria are membrane bound cell organelles, associated with cellular respiration, the source of energy, being termed as power houses of cell. Mitochondria, discovered by Benda (1898), are present in eukaryotic cells. These are bean-shaped organelles, [...]
