During mitosis.....what happens to mitochondria ? Do they divide first, then get shared by the two daughter cells? Do they multiply once in the daughter cells ? What is the mechanism of their survival during cell division ?
@marknasia5293

mitochondria can multiply thru fission and can combine to fix dna damaged in the mitochondria thru fusion, mitophagy (breaking down of mitochondria) is a benefit if the mitochondria become very inefficient, preventing of consumption of ADP that could be used by more efficient healthier motochondria. so when the the cell goes thru mitosis, the number of mitochondria are shared, not sure what percentage. As the cell requires more energy, it triggers mitochondria to perform fission, and as a person becomes more sedentary, the mitochondria being so efficient, perform fusion, thus repairing any damaged motochondria and killing off some mitochondria that have become overly inefficient.

bellissima lezione - i mitocondri hanno diverse analogie con i batteri: Contengono cardiolipina, possiedono un DNA circolare tutto loro; esprimo 13 proteine che contengono FORMIL-METIONINA, proprio come le proteine batteriche, producono melatonina "proprio come il batterio viola Rodhospirillum Rubrum, hanno una doppia membrana, sono anche in grado di metabolizzare piccole quantità di solfuro di idrogeno, uno dei primi substrati energetici dei batteri primordiali, e vengono riconosciuti come antigeni batterici dal sistema immunitario.

I studied Biology at school (many years ago, 1962 to 65 or so), so a bit late for me to study mitochondria) and I knew about them as producing ADP (adenine diphosophate) and that they were on the endoplasmic reticulum...what great words. I think I just liked the pictures and the words of things and so on but I don't think anyone knew much about them having DNA, there own. Yesterday I would have laughed if someone had said there is DNA in the mitochondria. 'No, DNA is in (most) cells, in the nucleus...But I was reading a book by David Reich about how (where we come from etc) and mitochondria were mentioned versus a Y chromosome so I was assuming he was talking about mitochondrial DNA meaning the genes in say the X Chromosome or wherever or a part determined at 'genesis' by the nucleus (DNA) of the ova, a gene that "made" the mitochondria. At least it was informative. Everywhere (or, all the very naive ones which are good for people in a hurry I suppose) else they just say 'M-DNA is DNA inherited from the maternal....' But either my hearing (when I was in my late 30s in a Comms lab someone made an audio freq oscillator and (I wasn't surprised) my hearing cut off about 20Khz. I suppose as I am nearly as old if older than Trump my hearing is worse so I had to re-run a lot of this. Her accent sounded sometimes like she was talking in German or French...something like that. Bad diction a lot of English and American people have, or bad for me...perhaps it is a special dialect from some place in the US no one has heard of or I am even more deaf to those high frequencies... I find, for some reason, this to be fascinating, but it is also terrifying and reminds me of death.

The mitochondria is indeed fascinating. But it's ironic to hear such a strong sales pitch for evolution using the organelle that so clearly demonstrates intelligent design. For example, consider the proteins. There are a *_lot_* of different proteins in the mitochondria. Proteins must fold correctly to be useful and they have to form the right shape and expose the right amino acids at the right places to perform their task. Did all of those proteins evolve? If not, where'd they come from? If they did, then surely there are a fair percentage that aren't quite done evolving yet, that don't fold compactly yet, or that don't fit together neatly with the other proteins components. What percentage of proteins in the mitochondria aren't done evolving? Many proteins have no value apart from being a component in a complex or machine. As the various proteins evolved, why did natural selection conserve them until the other components of the complex completed their evolution? Did natural selection see the evolving purpose? And as each complex in the electron transport chain evolved to functional completion, why did natural selection conserve the whole complex before ATP synthase had evolved into place? The fascination comes from the wealth of molecular machines and their protein components that all function so smoothly to perform such complex chemical processes and even proton pumping. The whole thing is amazingly well designed.

@@itsReallyLou Direct observation (an aspect of Occam's razor) tells me that the intelligent things that intelligent agents do are also always the consequence of physical brains. Occam's razor doesn't really lend itself to the invocation of supernatural agents anyway, so you might want to rethink that. Psst.. complexity can accumulate incidentally, and when people design things "for reasons" the complexity usually isn't a selling point but instead a necessary "it is what it is" consequence of having to juggle and compromise btwn various demands from within and without. It's almost as if declarations of complexity are Inadvertent admissions that "the designer" was constrained by aspects of its own creation. I guess that's why dogs can only sweat near their paw pads.

Not all fatty acids are equal in energy production.Saturated animal fat produces 100% efficiency, mono saturated fat 115% due to the bond opening in the center is a easy snip, now you have 2 smaller sable saturated fats.PUFA's (polyunsaturated fatty acids) are highly oxidative and in metabolizing them produce toxic by-products.Omega 6/ linoleic acid has a 60% efficiency and Omega 3/linolenic acid has 24% efficiency. These heart healthy fats are anything but.Seed oils are damaging energy production from the mitochondria watch KZitem video's of Dr Cate Shanahan, Dr Michael R Eades, Dr Chris Knobbe, Nina Teicholz, Dr Paul Saladino
