Abstract The structure and function of mitochondria have been characterized with increasing precision. How the protein inventory defines characteristics organelle remains insufficiently understood, however. Recently we devised a quantitative proteomic approach to estimate copy numbers proteins in single plant mitochondrion, as physical operational unit cell. We illustrate how such simple though...

Diverse biological data may be used to create illustrations of molecules in their cellular context. I describe the scientific results that support a recent textbook illustration of a mitochondrion. The image magnifies a portion of the mitochondrion by one million times, showing the location and form of membranes and individual macromolecules, revealing the molecular basis of its role in energy ...

human mitochondrial dna (mtdna) is 16,569 base pairs (bp) in length, coding for 37 genes. during the course of evolution, nearly all the genes expressing ribosomal proteins and ribosomal rnas (rrna) genes have been transferred from the mitochondria to the nucleus. however, mitochondrial dna contains two ribosomal rnas genes (12s and 16s), which have not yet transferred to the nucleus. these two...

Cytochrome oxidase activity via cytochrome c, as demonstrated by the diaminobenzidine procedure, has been employed in this electron microscope cytochemical study to determine the respiratory potency, integrity and fate of the Arbacia sperm mitochondrion at fertilization and during early embryogenesis. The sperm mitochondrion remained intact and was intensely positive for cytochrome oxidase acti...

If your body were a train, what would give it the power to move? The food you eat, which is burned by train’s engine. Do know how many engines has? Thousands of millions! They are called mitochondria. Mitochondria tiny structures contained within cells that burn food, providing energy. each mitochondrion due its own gearwheel: circular mitochondrial DNA. There gears in mitochondrion. Together, ...
