- Mitochondrial Dna Organization Is Variable
KEY CONCEPTS:Animal cell mitochondrial DNA is extremely compact and typically codes for 13 proteins, 2 rRNAs, and 22 tRNAs. Yeast mitochondrial DNA is 5× longer than animal cell mtDNA because of the presence of long introns. Animal mitochondrial...

cytochrome
Term: cytochrome, literally meaning ?cellular color? because cytochromes are conjugated proteins containing a ferroporfirin pigment
Origin: Anc Greek
?????/kytos (=container, box)
Greek letter K is replased by latin C, like in word ?cycle? which is derived from word ?kyklos? and it is used as a combining form meaning ?cell? in the formation of compound words like cytochrome, cytogenetics etc.

> ????/hir(=hand)< ??????/hripto(=touch or anoint)
Coined
Cytochromes were initially described in 1884 by C. S. McMunn (1852?1911), as respiratory pigments and later in the 1920s, the Polish David Keilin (1887?1963) rediscovered these pigments and named them cytochromes in his paper ?On cytochrome, a respiratory pigment, common to animals, yeast, and higher plants? (Proceedings of the Royal Society, 1925).
Definition
Cytochromes are membrane-bound hemoproteins that contain heme groups and play an important role in cell respiration as catalysts of oxidation-reduction.
