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 [...]
In this article we will discuss about the Anatomy and Functions of Mitochondrial Membrane. Anatomy of Mitochondrial Membrane: 1. The outer membrane of mitochondria is permeable to most metabolites, but the inner membrane is selectively permeable. 2. The inner membrane has a matrix and the inner membrane is thrown into folds or cristae. 3. The presence of monoamine oxidase and [...]
