Mitochondria - Jodi Nunnari (UC Davis)

Dr. Nunnari explains that mitochondria are derived from prokaryotes and played a pivotal role in the evolution of eukaryotes. In an aerobic environment, mitochondria produce energy, in the form of ATP. This energy allowed eukaryotes to develop into complex cells and organisms. Mitochondria are also fascinating because they have retained their own genome and are dynamic organelles that communicate with other compartments in the eukaryotic cell.

what an awesome woman. how lucky her students are to have her as an instructor.

So they're not just the little kidney bean energy factories that I learned about 50 years ago. So cool to see how both they and our understanding of them have evolved.

Thanks for the video, just an interested person in science in general. Seems we have plenty to keep us busy investigating and discovering in the future.

I learnt so much from such a well delivered talk. Thank you.

[ErikS-]

Great talk!
You really get taken into the subject by her enthousiasm!

[rsdaarud]

What a dynamic and essential organelle!!

[romanowskiart]

Awesome Video, thx, if Back in school days you thought me biology, I Might have been interested enough to remember This stuff after 40 years...thx again

[PlaceboFutureHealthCare]

Thank you so much for this easy to understand and visually rich teaching presentation! 💚

[dilipsinhjhala]

Very good information !
Thank you very much for sharing

[isejanus]

Finally! A YouTube channel for Kreb's cycle enthusiasts!

[luli]

Thanks for your amazing lecture gives us so informative knowledge

[Petrov]

Outstanding -- I am not at all an expert in this field -- but read all four Nick Lane's book

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.

You very well convenienced us and I want a next level video on this from you..

I assume that there is a rhythm to their action that is concordant to breath. If so, then how one breathes affects their action.

[julioequinones]

Wow! How about in plants? Do they form this reticulum?

[gonicjon]

great talk...i take pqq for increased mitochondrial performance and energy production...i know i don't get enough sleep..., but what other health hacks do you have? i saw nad and nadh on your chart... i think i've heard it mentioned in other mitochondrial maybe some more citric acid to boost up/have available for the citric acid cycle

[GregMeadMaker]

Thank you for your wonderful presentation! What have you learned in relationship to the role that the ancient molecule melatonin plays within the mitochondria? -- Audrey

[variolaa]

Hi Jodi
what happens, if you isolate people and poison their mitochondria with e.g. fluoroquinolones in respirators.... and the person doesnt have a chance to come in contact with other people and their mitochondria, so that they can exchange each other and repair mitochondrial damage... just like bacteria do it if harmed with transcription and stuff like this...?
Thank you for this wonderful presentation.

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.
