Mitochondrion (band)
Mitochondrion is a Canadian black-death metal band from Victoria, British Columbia, formed in 2003. According to music critics, "What makes Mitochondrion stand out is their ability to bring order to chaos. [...] wikipedia.org

Proto-mitochondrion
The proto-mitochondrion is the hypothetical ancestral bacterial endosymbiont from which all mitochondria in eukaryotes are thought to descend, after an been proposed as the alphaproteobacterial sister-group of mitochondria, there is no definitive evidence as to which alphaproteobacterial group the proto-mitochondrion wikipedia.org

Was the mitochondrion or chloroplast first? I still don't know if the mitochondrion or chloroplast was first? I've looked for it on the internet and in various books but haven't found anything. Does anyone have the an...
Mitochondria evolved before chloroplasts. We know this because Mitochondria form a monophyletic group: e.g. all life with mitochondria traces back to a single common ancestor (source). Since the group with chloroplasts groups within this clade, it must be the case that either (a) chloroplasts were o...

Mitochondrial processing peptidase
This enzyme catalyses the following chemical reaction Release of N-terminal targeting peptides from precursor proteins imported into the mitochondrion In order to achieve this, many mitochondrial proteins encode a short targeting signal which directs them to the mitochondrion and through its preprotein wikipedia.org

Are cells guaranteed to get at least one mitochondrion when they divide? If mitochondria exist at random within a cell, isn't there a possibility that cell division will result in a daughter cell with no mitochondria?...
> Isn't there a possibility that cell division will result in a daughter cell with no mitochondria? Yes, there is always the possibility. However, there must be a strong negative selection pressure against eukaryotic life that cannot achieve the proper partitioning of mitochondria, so you can imagin...

STARD7
Function and tissue distribution StarD7 is found in the cytosol and associated with the mitochondrion. StarD7-I possesses an additional 75 amino acids at its amino-terminus, which form a signaling sequence that targets it to the outer membrane of the mitochondrion wikipedia.org

Diffusion of FAD+ Why is NAD+ free to diffuse within the mitochondrion whereas FAD+ is not ? What biochemical properties cause this difference ?
As explained at the Wikipedia page for succinate dehydrogenase the FAD is covalently attached to one of the subunits of the protein. It is the first carrier in a short **intramolecular** redox chain involving Fe-S clusters, and possibly a haem, before the electrons derived from succinate are passed ...

POLDIP2
POLDIP2 / PDIP38 is a moonlighting protein that has been identified in both the nucleus and the mitochondrion Interactions In the nucleus, POLDIP2 has been shown to interact with PCNA, while in the mitochondrion POLDIP2 has been shown to interact with proteins constituting the mitochondrial DNA nucleoid wikipedia.org

Membrane Permeability to Pyruvate Pyruvate seems to pass easily through the outer membrane of the mitochondrion but has difficulty entering the inner membrane (and gets in by H+ symport). I have two questions: (1) wha...
Pyruvate is negatively charged and quite polar, which makes it unfavourable to diffuse directly through any membrane. The outer mitochondrial membrane contains porins), which allow small molecules, like pyruvate, to passively diffuse through. Specifically, pyruvate uses voltage dependent anion chann...

Apoptosis-inducing factor
Normally it is found behind the outer membrane of the mitochondrion and is therefore secluded from the nucleus. However, when the mitochondrion is damaged, it moves to the cytosol and to the nucleus. wikipedia.org

What's the use of RNA editing in kinetoplast? The genes of the mitochondrion (kinetoplast) of some _Kinetoplastida_ \- e.g. Trypanosoma brucei, the parasite which causes African sleeping sickness - are "encoded" in a ...
You could have asked a similar question about splicing. The function of RNA editing seems to be similar: it's one of the ways to trigger production of alternative transcripts and proteins given the same DNA sequence. The question is discussed, for example, in this review. The authors describe differ...
