Mitochondria

Very interesting, bump.

how does a cell live without the powerhouse of the cell?

who supplies the green pancakes?

How does he know they are happy?

Prokaryotes live just fine without mitochondria. Seems like this eukaryote acts like prokaryotes in that regard

love how the guy in the article puts forward an incorrect definition of what a eukaryote is just so he can big himself up, although tbf this is huge

What about red blood cells?

>>8070104
True but prokaryotes tend to use transmembrane enzymes in energy production but in the article it says this eukaryote uses cytoplasmic enzymes

Don't...

Don't mature mammal red blood cells exist without mitochondria? Is this really groundbreaking?

yeah they dont have mitochondria or any other organelles for that matter but its not like they survive for that long anyway since they are dispensable and dont have any alternative forms of energy production.

need to look at it from an organismal level rather than a cellular level, this eukaryotic organism makes zero use of mitochondria, cant say that for any others

>>8070116
The key thing is that a eukaryotic ORGANISM doesn't have Mitochondria

>>8070137
actually its eukaryotic organisms that DO have mitochondria and prokaryotes that dont

>>8070137
My bad, should have actually read the article instead of knee-jerking like an idiot.

That's a really interesting discovery, but intuitively I'm not surprised something like this is possible. We already see similar workarounds to celluar energy mechanisms with some endothelial cells. Bookmarked regardless.

>>8070151
What workarounds are there in endothelial cells?

There will always be that one exception huh?

>>8070119

their precursor cells have them, they just lose all of their organelles on the way to becoming fully mature and functional.

>>8070056
Not terribly surprising, probably just using an inefficient form of energy harvesting. Maybe fermenting?

The eukaryotic cell with a mitochondrion is dominant for a reason.

It'll probably get disproved later on

interesting, will keep on my radar

So how does this change things?

>>8070720
>This is the first example of a eukaryote lacking any form of a mitochondrion, demonstrating that this organelle is not absolutely essential for the viability of a eukaryotic cell.

And evolution just keeps falling apart.

Crispr would help

>>8071823
How?

>>8070064
Glycolysis

>>8071811
You're a fucking retard cunt.

GUYS, THIS ORGANISM IS AN ANAEROBE.
They weren't expecting it to need mitochondria for oxidative respiration the way we need ours; the cool thing here is that the mitochondrial genome, with all its contributions towards the organism's protein synthesis, seems to have been either reduced away to nothing or has migrated entirely to the nucleus (or some combination of the two). THIS is what's cool beans.

>>8072016
What does it being an anaerobe have to do with anything?

If it doesn't have mithochondria then it can be attuned to the force

Obligate, aerotolerant or facultative?

have another beer, Homer

>>8072909
mitochondria arn't used in anaerobic energy production.

stop posting

Nice that the wiki page updated https://en.m.wikipedia.org/wiki/Monocercomonoides

Giardia lamblia is also an eukaryote and doesn't have mithocondria. Is not a big deal.

>>8074800
Giardia lamblia still has remnants of mitochindria. We're talking about an organism that doesn't have any at all

>mfw our department just switched to new biology textbooks

>>8075072
Thanks bro
I was writing on my cellphone, so...

>>8070056
Cool find OP. Just wonder what else isn't essential
