[@ross-carlson]

My biggest take away from this video - time/history is FUCKING VAST. I really started to contemplate the deep time it took for this to evolve natural. The billions of billions of billions of billions of billions of reproductions, virtually all of them failing but enough survive due to natural selection to create this symphony of nature. And, as you say, the amount of human knowledge and time spent gaining that knowledge condensed here is also staggering. Thousands and thousands of human life times of asking "why" and not accepting "god did it".

[@misovejasescuchanmivoz]

@@ross-carlson You are delusional if you think these extreme complex processes exist due to chance and time. You can see extreme and complex processes in nature like in time and space laws, gravity, seasons laws that are in perfect harmony with existence allowing these organic machines to exist as they do, things like eclipses which have the moon and the sun in the perfect size so we can see them from earth, or mathematics, where did math come from, was it created by chance? if you think everything in existence is made by natural selection you have more faith than I do.

[@kampfmuffin3535]

[@albertomolano]

Think of an AA battery: it has a (+) pole and a (-) pole. The (-) pole wants to "give" electrons, the (+) pole wants to grab those electrons. The flow from (-) to (+) generates the energy that lights up a flashlight. The FOOD you eat is like the (-) pole: it has electrons that can be easily removed. The OXYGEN you breath is like the (+) pole: it wants to grab those electrons, badly (that's why it also rusts nails). The mitochondria is where electrons from food jump through a series of intermediate protein complexes with higher and higher affinity for electrons, and end up swallowed up by the oxygen you breath. That flow provides the energy that keeps you alive.

[@fatimamezouaghi9780]

Alberto Molano thanks😊

[@albertomolano]

You're welcome. I have always thought this is one of the most amazing discoveries in the history of science.

2:29から　水の分子はマトリックス側にできるのに、このアニメでは膜間腔側にできている。これはまずい。 2:29　Water molecules are synthesized on the matrix side.But in this animation, molecules of water are synthesized on the intermembrane space side.

[@aspektx]

Seeing things like this makes me realize how inconceivable the stretches of time are for things like the mitochondria to develop. All the failures, the variations that partially worked, and the diversity that must have occurred on the path that led to something so small and so significant.

[@ahmadrashid4853]

if ATP synthase came about by millions of failures to be this perfect and in harmony, all the other times it failed would not be possible because if it did not work the first time, the creature would not be able to live long enough to replicate for mutations to have a chance of occurring so it is impossible. It is like saying a human without a heart had children who then had 1/4 of a heart and their offspring mutated a proper heart which is impossible because if it wasn't perfect at the beginning, the creature would not have survived to be able to replicate in the first place.

[@electricity2703]

I agree with you all guys. How can these complexes develop by chance even by natural selection? It is impossible.

[@tacitozetticci9308]

@@ahmadrashid4853 nope. It used to work differently but it did work. You can get hints at how the older systems were by looking at more ancient creatures like the anaerobic bacteria. Yours is just like the classic "what use is half an eye?" argument, but we know it's not a bright argument. A simple eye can only distinguish between dark and light, it could be a sensitive surface appearing somewhere on the skin, but that's okay because that's already an advantage and the mutation will survive. Eyes have developed separately tens of times, and so did the different ways of distillating energy like ATP synthesis. The fact that now we're stuck with these organs and we need them to survive doesn't mean that it was always the case. Many creatures live without hearts and circulatory systems just fine, they'll just dissolve the nutrients in their body and that's it.

[@o_sch]

@@ahmadrashid4853 no, either the cell had some other way for energy or the small individual things like proton pumps randomly formed and there were millions of failed versions beforehand.

[@ahmadrashid4853]

@@tacitozetticci9308 So where is mid stage ATP synthase with half a rotor missing?

[@higherresolution4490]

At MINUTE 2:45 a mistake is made. Complex II does not pump protons into the intermembrane space. Complex I, III and IV do that job of creating the proton motive force that drives the 8-proton rotation cycle of the ATP Synthase turbine.

Ok so here are the mistakes i gathered. Complex II doesnt transport protons, only I, III and IV do. The animations shows water molecules being produced in the intermembran space at complex IV, when actually they are produced on the matrix side. The subunit Fo of the ATP-Synthase is called Fo and not F0. O stands for Oligomycin. Finally the rotation of the ATP synthase is depicted in CW direction, but it actually spins CCW. Still amazing animation tho.

[@joshuawalker8297]

Summary This video explains the structure and function of mitochondria, the organelles responsible for producing ATP in eukaryotic cells. It details the process of protein transport, cellular respiration, electron transport, and ATP synthesis within the mitochondria. Highlights Mitochondria are organelles responsible for producing ATP in eukaryotic cells. 💡 Most mitochondrial proteins are transported into mitochondria through specialized protein translocator complexes. 💡 Cellular respiration, which involves the oxidation of carbon fuel molecules and production of reduced electron carriers, occurs in the protein-rich matrix. 💡 ATP synthesis is driven by the proton motive force, which is created by the pumping of protons across the inner mitochondrial membrane. 💡 Mitochondria can undergo dynamic changes in shape and distribution, and perturbations in their behavior are associated with programmed cell death. 💡
