Photosynthesis (Light Reactions) 

A picture is worth a thousand words; a video maybe a million.

the intro kinda spooky ngl

This is amazing, about 1000 times clearer than my bio professor

Amazing video, explains 20 pages of my university book in only 5 minutes!

Finally see the big picture. I have been struggling for too long

Well paced, and a great presentation. Thank you for your service to increase the level education available on the web.

2022 and this is still one of the best of its kind on youtube

Photosynthesis blows my mind. The narrator has a delightful voice. Great job.

thank you! as a 7th grader studying this it really helped! we watched this in science class too, and im studying for my quiz now so i watched it again. this is an amazing vid if you dont understand science class!

Finally, you are the one I've been searching for all of my life

Thanks for uploading this video. It simplifies what the Biochemistry books make complicated.

Thank you for this video! It clarifies everything really well and is a great study tool. Keep up the great work!

Wow - your animations are always incredible. Thank you so so much. You word everything really well - very easy to conceptualise

That makes so much more sense. I had no clue why the photons were necessary to excite P700 but now it makes total sense thank you!

guys, this is way better and easier than these crappy textbooks. This really saved my life.

Some have complained that this presentation is too complex. It was designed for a specific audience, not the general public. The complexity, depth, and detail of a presentation all increase as the abilities of the intended audience increases. I sure wish I had seen animations like this during MY education.

Photosynthesis makes so much more sense now, the light dependent cycle anyway. Thanks!

Beautifullll Love the animation and the girls voice is pleasing to the ears

Amazing videos!!! Without you I would never pass this exam!

It's amazing how those micromachines are really molecules, different shapes and combinations for specific purposes.

Let's gooooooooooooooooooooooo!!! Bio Test

excellent video, fantastic. best photosynthesis vid I've watched yet.

In adittion to this process, after the reaction between co2 and the ribulose diphosphate, the "Calvin Cycle " uses the nadph and ATP produced in the light reactions to synthesize glyceraldehyde: a carbon molecule. After that, the glyceraldehyde will eventually become glucose, which will be used by the mitochondria to generate energy, and a part of the molecule predecessor of the glyceraldehyde will stay in the cicle and will become ribulose again, react with another co2, and so on .... life is beautiful in its simplicity :D

ehh, thanks for introducing me to the internet? i wonder where i would be without you?

These videos are great! Now I know where to look when I need a summary of a lecture. Thank you vcell! :D

when i first watched this video i thought i was screwed, but then i did a little googling on: ATP, NADPH etc. and got more confused. Then I went and watched a few other videos from this animator on electron transport chains, ATP and finally revisiting this video. Long story short, everything now makes complete and utter sense, just stick with it for a little while and the sense will come eventually...

This helps clear up my confusion for a quiz tomorrow!

Thank you for having the info at the beginning, thank god.

wow. it was cool because it showed the process from the inside! very informative.

Wow this just makes everything so clear and makes perfect sense! :) Its great to have such videos to study with!

really great animations. much easier to be interested in than a narrative written in a textbook. my big question is, how did all of this get discovered??

Woa, I kind of got that. Thanks for such a cool visual on photosynthesis.

it took me about 30 minuets to write all this down because i need to know it for a test but it helped soooooo much it was really worth it. -thank you

I'm reading Oliver Morton's "Eating the Sun..." (Layman's guide to photosynthesis discovery) but got lost in the details. This animation was exactly what I was looking for to help visualize the process. Thanks so much.

Damn I feel good as hell right now! Watched this video earlier and was confused, but after reading a chapter in my textbook and taking notes, this rings a bell at almost every stage of the photosynthetic process! Only thing I didn't encounter in my book is this "lumen."

Excellent video, elaborated on my professor's lecture.

Amazing !! It became so Simple after watching This !!! Thanks a lot ... :)

Extremely vivid!! Thanks for uploading :))

Fabulous! Though they may not realize it, students today are blessed by the paradigm presented in the power of 3D animation. After all, could you *ever* get such a lucid comprehension of such an esoteric subject with nothing but a person in front of a blackboard rolling off a string of acronyms? Excellent work, all of you. One question: where does the hydrogen go?

Perfect visual explanation! Woow! Nice job guys! Put online more!!!!

I finished biology recently enough to still understand this! Yay! =D

thx i always wanted to know about photosynthesis!

you should deserves medal

clear and well animated. good job. helped me understand better. thank you.

biology is all about seeing and relating and watching videos gives us the actual feel of what is really taking place so we understand better. teachers need to know that

this wuz very helpful, i saved me from failing my midterm!!

REALLLLLLLLLLYYYYYYY AWESOMEEEE!!!!!!!! you only have 19 vids, but really helpful ones.

Ah! So complex, yet so perfect.

Thank you for explaining the process of photosynthesis.

Very educational! I finally understand photosynthesis.

SUPER VIDEO.WORTH OF 1O HRS OF TEACHING

super video that explains in 5 mins in which i was struggleing to learn this from 3 days

Excellent video. Thank Youuu!!!!

ndsuvirtualcell you guys are awesome

ahh biology midterm tomorrow and you saved me! thank you!

please please please please please post more of these i love science!!!

excellent and simple. All these extra stuff from my biochemistry book made me wonder what is a bigger picture of how these 2 systems work?))) now, it is clear, and I can start working on the details.

Resonance? Are you kidding me? That's some crazy stuff there man.

I slept in class room when my biology teacher was explaining about light & dark reaction. The boring period of my school life is biology Not due to subject but due to teacher

by far one of the best animations regarding e- transport chain and photosynthesis out there =) thank you for this!

Science is the best subject. NOTHING IS BETTER THAN SCIENCE.

AWESOME keep making videos like these please!

This video helped! My friend & I are attempting to understand this for a big test we have tomorrow!!! This helped, if we fail, will be re-commenting! haha

That's why the "light reactions" part stands in the brackets there. The Calvin Cycle is obviously not included, as shown by the title.

Really clears up what all those text books attempt to describe using only text.

This is awsome. Thank you for showing us this.

it takes a lot of lower level stuff to make a single cell work..but basically it boils down to matter and energy. Good video. I would like to see one that explains how these functionalities originated from simpler chemical compounds.

Wow,, best explanation I have ever seen on photosynthesis.

Photosynthesis is split into the light and dark reactions, iirc. One uses light and electrons to make a gradient, and the dark uses that gradient like water-behind-a-dam to force CO2 together. I think by the end of the video, CO2 was in the form of NADPH.

Animation and imagination is the best way to understand each part of biology clearly and enjoyfully also ,love this way of study specially in biology O my god ,this video is 13 years old

great video. simple and to the point. 5 stars

Thanks for making it simple and informative!

I understand this while my teacher is discussing this, but you explained it very well! Thanks! I am not confused now, :)

Brillaintly explained ... clear now!

one of the best step by step animations i have seen for any process. too bad studying this shit for hours on end won't prevent me from forgetting it in a week. fuck biology man why is this my major?

esta es la prueva clara que los conseptos impartidos en nuestras facultades estan no solo atrazados sino comprometidos, pues estamos formando personas sin informacion ni conseptos basicos para entender los desafios actuales. valio la pena descubrir esta video educativo.

thanks dude.. this vid really help me out.. :D

cool !! man this video makes photosynthesis a lot more understandable.

woooooow i am so amazed.... wow

you are AMAZING!!!

luv this video. 5 minutes of new information much better than the hour of blahblahblah my science teacher throws at me.

You're funny. =] I'm glad to hear you knew all about Andenosine triphosphate and methoxy-hydroxy-phosphoryloxy-hydroxy-phosphoryloxyphosphonic acid in sixth grade, not many people can boast as much. I was taking dual courses Bio-Chem, and we only learned about it last year. That must have been one advanced middle school. =]

perfect demonstration

Absolutely astounding.

damed why cant i find a real phtosynthesis video !! ... btw this is the best i have managed to find !

woah this is so detailed. Way better than my book

woww.. super helpful for my basic biology class.

This video make the easier to understand the light reaction proces...... Thnx... A lot ...🙏🙏

Thanks a lot for those videos, a great helping to show in class...however, I'd like to request for the calvin cycle to complete the explication, millions thanks again :)

wow this is great!!! now i understand it more!!!!!!!!!!

helped me pass my 7th grade bio test very good.

It is helpful! Thank you!

Yeah this video is REALLY DEEP, don't bother watching it unless you're doing Biology at a high level

I'm a first year university student and we do photosynthesis in biochem. The chapters are full with details and are way too long so I lose the whole picture by the end of the chapter! This is a great summary!

Yep, great animations :D

This is so clear thank you!

Magnificent presentation.

I didn't know that inside a lead is so complex. Next time, I will greet every tree I pass by!

Isn't it helpful to know how much work is happening in plants as their cells preform this unique process that helped to change the atmosphere of the earth, which ultimately, helped you and all other humans to be able to survive on this planet today?

i love the intro music for this video :) :)
