Mitochondria

My greatest gripe with people who discuss the many facets of life-energy is the seemingly complete and utter lack of knowledge about mitochondria.  I'm not talking just the spiritual folks and chakratics; there is little mention in any of  the quadrants.  Not even our pal Ken Wilbur seems to devote much to the lowly mitochondrion (the singular), but I've only checked the index of the 3 books I own (having only recently discovered and subsequently been repeatedly astonished by him).

Why are mitochondria so important?  The most common metaphor in the biology texts is that of the “cellular power house”.  Every cell in every animal (and many plants) has at least one mitochondrion, and some (like the muscle cells) have thousands.  Mitochondria (to brutally simplify things) transform sugar into ATP (adenosine triphosphate).  The third phosphate on this molecule isn't on very tightly, and if it breaks off, energy gets released.  This is the energy that our cells use to do whatever it is the cell needs to do, whether it be release a neurotransmitter, contract or reproduce.  Without mitochondria, our physical bodies would be dust.

Another aspect of mitochondria which is of vital import is this:  it has its own DNA.  It is not us.  We use the mitochondria in our mothers' ova (sorry dads, your mitochondria is a genetic dead end) and it reproduces alongside our own DNA, utilizing many of our mechanisms, much like a virus does (but it doesn't inhibit our own, so it's not viral).  

No one is sure how our cells began this deeply symbiotic relationship.  Either the mitochondria was consumed by a larger single-celled organism and it proved difficult to digest or it was a parasite that was co-opted because it excreted a useful product.  Either way, two distinct lifeforms stopped competing and began cooperating for the betterment of both.  If there is a better definition of soul, I don't know it.

The fact that this relationship allowed for multi-cellular organisms like me and my cactus and the spider that weaves dew-laden webs for the morning sun to glisten in is a blessed side effect
