Light-dependent reactions of photosynthesis

Please view this video on my new channel, @shukinscience !

All content on my current channel (& more!) will be moving there soon.

1am and i have a final in a couple of hours thanks for this

[thatkidwhoyoudontknow]

This was by far the most detailed but simplified explanation I found! Understood it right away! Thank you.

[Simply.simbiat]

This is by far the best tutorial on YouTube in this topic. You just saved me thanks a lot

I think this is the first time I have seen it broken down to steps, that makes it so much easier.

Except that she has the suns rays coming from the Thylakoid lumen and not the Stroma. The Glorious Clockwork has a great 4 part series on photosynthesis

dude the fact that this absolute angel of a person taught me everything that my biology teacher taught me in 3 hour-long lectures in under 10 minutes is absolutely wild. Thank you so damn much you just saved my grades :)

[pptesting]

This was a very helpful video! Thanks a million for this precise and detailed explanation 🙂

[noeditbookreviews]

Everything about this production is in maximum agreement with how I like educational video. 10/10. I wish more were just like this.

[samaraarain]

perfect video! I actually thoroughly understand this more now.

I'm sorry but you leave out many details. It's not only your video. every video on photosynthesis does. biology makes no sense without physics. obviously there are some electrochemical or electric processes going on but bio doesn't even touch the subject. 1. where is the water and where does it get broken down? is it in the stroma or the thylakoid or the psii? and you should probably write the equation as 2H20 -> 4(H+) + O2 + 4e- as your equation is not even balanced. And why in the world would the electrons released from ps1 and ps2 be different if they are both energized by a photon of light? The ps1 must have a lower work function so since its lower energy it goes into the stroma? why wouldn't it just get into another ps1? or go into the stroma to create nadph? I'm assuming the ps1 and ps2 are randomly scattered throughout the membrane. the electrons from ps2 lose energy because... ??? . does the membrane act as a catalyst to break down water so that you can have O2 escape into the atmosphere and the 2H+ go into the thylakoid? or doe psii act as the catalyst?

Thank you so much for this explanation! I'm studying for my exam in the next week, and your video helped me so muchh<3
obs: english is not my first language :D, the other professors(of my country) are so confusing so here I am

[abbyhanifin]

Really helped me!! I was so lost before watching. I aced my quiz :)

[kyukyo]

u just cleared every confusion i had, thank you.

[malak]

This was so much more clarified and easier to understand, tysm!

[sbhupathy]

Excellent explaination about photosynthesis thank you

[clwells]

Thank you, I was getting so frustrated by other vids. This was excellent!!

[askiaso]

Thank you so much! This helped me understand the process so easily compared to other sources :)

Some missing points:
1)PS2 can be called P 680 as it's activity is higher at wavelength of light. Similarly, PS1 is P 700.
2) OEC the oxygen evolving complex is what actually causes photolysis of water. It is associated with the PS2 towards the lumen of thylakoid.
3) PS2 are absent in stroma lamellae, which results in cyclic ETS and cyclic photophosphorylation. These are solely dependent on PS1.

I always come back here whenever I have a biology exam

[colleenk]

this helped me so much! thank you thank you thank you thank you!

[assefadaba]

The way you explain is so satisfying 👌. Nice job keep it up 👏
