Hello from Montreal! 🇨🇦 Keep going! Your vids are excellent.🌟 3:12 Lumen: “the inner light” Not only pass by: if you’re having salad you’re eating those indeed amazing PS2 machines. Taxonomy and toponymy and terminology is like a game. It’s never logical. Like the generation of stars, Gen I are the youngest, Gen III are the first stars that appeared... But renaming would be even more confusing. You use any hook, and the sillier the better. Famous one for classifying stars: “Oh Be A Fine Guy/Gal Kiss Me.” That’s what I did in my pharmacy tech classes to help me memorize 600+ meds!

Well that means the world to me! Especially considering that I never would have figured out to resolve a model of the OEC or any of the reaction center without your active site tutorial for pymol! Those videos took me all the way from "fetch 1S5L" to this final 2d explainer!

I don’t usually comment but I just wanted to say that your explanation at the end honestly made me emotional. I majored in biochem because I knew it would be useful for other things I’m interested in, but the way you connected it to how everything in the world goes together so perfectly was brilliant, and I’m so glad I can see it that way now. Sending you and your channel lots of love and support

Yeah, he sums up the importance at the end and adds the science. I added the first three videos in this playlist to emphasize that importance, that's it's way way more significant than "just breathing oxygen", it's everything we know because plants are primary consumers. kzread.info/head/PLgRoK-eyLjok8nAxTUy5IuKb_c3Qefwsv&si=j_ImGFHJgzw8jb4W

Hi from London. Just wanted to say thank-you for your work. There is a lot to learn and go back to, but as you say 'that's part of the fun'. I have zero knowledge of biochemistry but this seems to be changing a little thanks to your videos. I always like the philosophy bit at the end, it brings the whole thing together in a nice light (no pun intended) Please continue.

Thank you for making the super-complex mechanism so clear! However, I have a difficulty understanding the part at 12:26 , where you say, "It takes four charges of photon energy to turn FOUR water molecules into a SINGLE oxygen ATOM, four protons and four energized electrons". If it's hydrogen protons you're referring to here, the way you describe the process, it has to be two water molecules, not four, either with resulting two single oxygen ATOMS or a single oxygen MOLECULE. Am I missing something or was it just a slip of the tongue on your part?

Wow, one of the most interesting channels and really well animated. Got yourself a new sub.

Beautiful Words. Our chemical machinery seems like magic, it's not magic, your illustrations help drive understanding. Thank you!!

Oh damn, what a great video. I was hooked after the Short and I thought “no way I’ll sit through all the chemistry” but it was SO INTERESTING!

Great video, I was looking for something a little more in depth and specific and couldn't find it, and expected that if I did it would be a typical dull and monotone or hard to process video. NOPE! Your tempo, rhythm and tone are perfect for me to mentally process (and your mic doesn't suck). Thanks.

I just finished a semester of biology in college and this video went over exactly we went over. Im glad to see such enthusiasm for science posted on youtube. Grear work!

Im not sure if your animation of electrons moving to P680 was accurate. If I remember correctly, the electrons are not jumping from pigment to pigment, but are doing something much more interesting. The electrons are staying in their respective pigments, but are transfering energy to other pigments via "Förster resonance energy transfer". As a Biochem student, it is something I have never heard about other than in PSII, so take this with a grain of salt.

Yea friend, I've been dropping DEEP in a research hole trying to understand that and make a follow-up video that explains that better. Turns out it's a bad idea to use papers from 2003 as your primary source -_- BUT--at the very least, it's giving me an opportunity to talk about some wild science in a follow-up video! The physics here is genuinely brain-melting.

This is so exciting.

awesome!

Even Archaeobacterias take energy from the sun, but very, very less direct compared to the usual ones. Thanks for the great video! EDIT: Seeing S2 - S3 gave me a lot of anxiety about those free floating oxygen atoms but I guess S4 resolves everything. It's like a composition that resolves in 4 movements. Pretty thrilling. Also that's basically a laser.

"I know it's weird that Photosynthesis started with the 2nd Photosystem, but it's only called that because it was discovered after Photosystem I." You know how invalidating that statement is for the generation that grew up with the Playstation 2? Heh that was a terrible quip. This video made more sense than the paragraph explaining this in my high school biology book. That's good enough for me!

Excellent video! It takes a lot of talent and hard work to condense such a complicated topic into a digestible KZread video. The only thing I would add to the conversation is that the production of oxygen was not universally beneficial. The evolution of photosynthesis changed the redox balance of the entire planet and stripped the oceans of their aqueous iron. Had the mitochondria not evolved to utilize molecular oxygen at the end of the electron transport chain, photosynthesis could have ended life on Earth!

Awesome video, you got a new sub! I do have a question, though. At 12:30, you said: "It takes 4 charges of photon energy to turn 4 water molecules into a single oxygen atom, 4 protons, and 4 energized electrons." Wouldn't the yield be 1 oxygen _molecule_ , 4 protons, and 4 energized electrons, as outlined at 4:07?

@seidojohn

4 жыл бұрын

I believe it also takes 2 water molecules. Each water molecule loses 2 electrons (e-) and 2 hydrogen atoms (H+), leaving behind the oxygen atom, which pairs with the other water molecule's oxygen atom to make a single O2 molecule. So shouldn't that line at 12:30 be: "It takes 4 charges of photon energy to turn 2 water molecules into a single oxygen molecule, 4 protons, and 4 energized electrons." I thought this video was amazing, and I am only trying to help. It's a lot to keep track of! :-)

Yea, and the insane part is that the line is written exactly like that in the script. I must have flipped the numbers while reading it. And then missed it during editing. And then missed it AGAIN during my final review. It's amazing the stuff you gloss over. Thanks for pointing this out and making it more accurate for people trying to use this to study! Y'all rule!

Nearly all life, as you mention, there are some chemotrophs. Also, physicists have given up on conservation of energy.

So this means most the water on earth surface are not old but being renewed everytime.

The author - please do not stop making videos. Though it is not so popular now - you will have fame among ancestors!... some of them are those being inspired of these videos =)

Have people attempted to create artificial molecules or mutating pieces of this process to increase solar energy capture? e.g., making the antennae longer or increasing the absorbable spectrum?

Tobias ERB has found a way to synthesize sugars from carbon dioxide and sunlight, without chlorophyll. The process is much faster. Cai, Sun , and Mu. Have recently done the same thing with starches We’re gonna need an update

I have no prior knowledge of the Kok's cycle and this video prompted me to look into it a bit deeper. I found from this 2018 article (www.nature.com/articles/s41586-018-0681-2?WT.feed_name=subjects_photosynthesis#:~:text=Inspired%20by%20the%20period-four,clock%20or%20cycle1%2C2) that there are transient states between S2 to S3 wherein a new H2O molecule binds to the Manganese-Calcium cluster. So, in actuality, the cluster is not empty, eveb when the final electron is ejected in S4 . That is, if I interpreted the conclusions of the study correctly. Hope you do more vids as great as this one! Big thanks!

That IS correct! And it was genuinely infuriating on my end to realize that I was using such an outdated model of the Kok cycle the day before I published! You can use my visualization as a foundation, but then drill down into papers like this: www.ncbi.nlm.nih.gov/pmc/articles/PMC6763417/ Now, one thing this paper goes into is that we're still fuzzy on the exact configuration of S-4, but at the very least you're going to get a way higher res view of S-0 through S-3 here. This research shows how the Kok Cycle is way more of a 'cycle' and way less of an 'event.' Use my representation as a foundation, and then level up into this understanding. Thanks for pointing this out! You have no idea how much joy it brings me that I made something that inspired you to look into it more. That is 100% why I work as hard as I do to make these videos accessible. It's all about giving people the energy and focus they need to dig deep into the real science!

It is incorrect to use the expression "hydrogen proton" (9:59). In Russian there is an expression "масло масляное (maslo maslyanoye)", which literally translates "buttery butter". It is used as an example of taftology, which, in fact, is the expression "hydrogen proton" It is customary to use either the designation "hydrogen cation" or just "proton", because, as explained further, a hydrogen atom is one proton and one electron, respectively, in the absence of the latter, only a proton remains.

Dope

Photosynthesis is an immense, mind-blowing process. This video covers the complex that starts it off: Photosystem II.

Great video. I never understood the climate narrative focusing so largely on Co2 as the main issue as opposed to other types of pollution and waste like deforestation, sulfur dioxide, plastic, so forth. Since of course Co2 is exactly what plants use to create energy and therefore structure. Does it not make sense that an increase in co2 would also cause increase in plant life?
