The Respiratory Chain and Oxidative Phosphorylation
The respiratory chain and oxidative phosphorylation are of utter importance for a cell’s metabolism. Here, the energy won from ingested food is being converted into our body’s energy unit (adenosine triphosphate). As the name respiratory chain suggests, oxygen also plays an important role. The following article will explain how exactly this complex mechanism works and which substances may disab...

متن کاملRespiratory Enzymes in Oxidative Phosphorylation
In a complex enzymatic sequence the site of action of substrates and inhibitors is clearly marked by the way they affect the steady state concentrations of the components of the system (1). Antimycin A, for example, inhibits respiration in the succinic oxidase system (2) and at the same time increases the steady state reduction of cytochrome b and decreases that of cytochromes c, a, and aa (3)....
متن کاملElectron Transfer Chain and Oxidative Phosphorylation
Chemically, oxidation is defined as the removal of electrons and reduction as the gain of electrons. Thus, oxidation is always accompanied by reduction of an electron acceptor. This principle of oxidation-reduction applies equally to biochemical systems and is an important concept underlying understanding of the nature of biologic oxidation. Many biologic oxidations can take place without the p...
متن کاملThe respiratory chain of plant mitochondria. II. Oxidative phosphorylation in skunk cabbage mitochondria.
Mitochondria were prepared from the spadices of skunk cabbage (Symplocarpus foetidus) whose respiratory rate with succinate and malate showed 15% to 30% sensitivity to cyanide inhibition, and which showed respiratory control by added ADP. The observed respiratory control ratios ranged from 1.1 to 1.4. The change in pH of the mitochondrial suspension was recorded simultaneously with oxygen uptak...
