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 :)
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 think shes just going off the specifications at college level, im in sixth form in england so comparable to the states college and the level of detail she was using is exactly the specification we need. i think the stuff your saying is more biochemistry degree centric
Hi everyone! Thank you all for your feedback. This video will soon be moving to my new channel, @shukinscience, so please like and subscribe for more biology content!
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?
This is a video meant for AP biology students. In the curriculum most of that isn’t something you need to know. I will say you are most definitely right, and she should’ve made note of those things
Thylakoids are tiny disks/circles that are surrounded by the stroma within chloroplasts, so it doesn’t matter which goes on which side. I chose to draw my “disk” on the top of the diagram, but you could draw it on the bottom if that is easier to picture.
i might be wrong but, shouldnt the formation of ATP from ADP be described as a phosphorylation process and not reduction since it is initiated by the energy flow from H+ trhough the synthase and not gaining e-?
Great question! Unfortunately, the amount of ATP generated through the light dependent reactions is just enough to fuel the light independent reactions... there is no ATP "left over" to be used by the cell for other processes. That is why plant cells must also perform cell respiration, as it generates very large quantities of ATP which can be used for active transport.
Light cannot be "split"... photolysis is the process wherein energy from light is used to split water. So, it is essentially just a special form of hydrolysis.

1am and i have a final in a couple of hours thanks for this
did you pass?
So did you pass
@@netad7771 yeah barely i got an 80%
I feel it
@CashCool420 80% is not barely passing lmao
This was by far the most detailed but simplified explanation I found! Understood it right away! Thank you.

This is by far the best tutorial on RUclips in this topic. You just saved me thanks a lot
Really helped me!! I was so lost before watching. I aced my quiz tyyyyy :)
do you have notes or anything that could help, I need additional resources for my test! Ty
This was a very helpful video! Thanks a million for this precise and detailed explanation 🙂
perfect video! I actually thoroughly understand this more now.
Everything about this production is in maximum agreement with how I like educational video. 10/10. I wish more were just like this.
My professor also wants us to know about how the antennae systems transfer energy to the reaction center. Not many videos talk about that.
Thank you, I was getting so frustrated by other vids. This was excellent!!
u just cleared every confusion i had, thank you.
This is gorgeous thank you
I’m happy to help! Check out my new channel, @shukinscience, for more biology videos.
Thank you so much for this explanation! I'm studying for my exam in the next week, and your video helped me so muchh
Excellent explaination about photosynthesis thank you
This was so much more clarified and easier to understand, tysm!
Simple and well explained love it❤️
you saved my life
very helpful! thank you :)
Thank you so much! This helped me understand the process so easily compared to other sources :)
I always come back here whenever I have a biology exam
Glad to be of some help! Check out my new channel, @shukinscience, for more biology videos.

For some reason my professor put photolysis in step 1. As though we get the electrons from photolysis.
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.

@deszu Ah I'm studying grade 11 bio for an upcoming exam too, but this information helped me understand better 😅

The way you explain is so satisfying 👌. Nice job keep it up 👏
You are my savior I love you
Yr vedios are helpful xem❤
I love this!! Thanks so much
There's a bit of error. The lumen/thylakoid should be on the lower part and the Stroma on the outside part.
Thylakoids are tiny disks/circles that are surrounded by the stroma within chloroplasts, so it doesn’t matter which goes on which side. I chose to draw my “disk” on the top of the diagram, but you could draw it on the bottom if that is easier to picture.
Well explained👍👍
i might be wrong but, shouldnt the formation of ATP from ADP be described as a phosphorylation process and not reduction since it is initiated by the energy flow from H+ trhough the synthase and not gaining e-?
but if plants can make ATP through light dependent rxns why does it need to undergo cellular respiration?
Great question! Unfortunately, the amount of ATP generated through the light dependent reactions is just enough to fuel the light independent reactions... there is no ATP "left over" to be used by the cell for other processes. That is why plant cells must also perform cell respiration, as it generates very large quantities of ATP which can be used for active transport.
Thank you mam great job
I have a final exam tmr, and this is coming. Really hope i do good, will keep you updated!! (i’m a freshman btw)
this was rlly helpful thank you!

awesome !
Thank you so much you saved me
She put the sun in the Thylakoid 💀💀💀💀
Yes, the whiteboard is only so big…
Wonderful
One of the Best tutorials❤
Very helpful🥺🥰🥰
السلام عليكم أستاذة انا مترشحة لشهادة البكالوريا في الجزائر🇩🇿شكرا لك دعواتكم لي بالتوفيق والنجاح🥺💗
I also wish you good luck !
Are the photosystems always arranged like this?
Thanks that was really helpful
i love u
thanks
for your help
THANK YOU SOO MUCH
Light enters the thylakoid without entering the stroma??🙄🙄
I have a final in 20 minutes thanks 🤠

where do the hydrogen ions in stroma come from, which is pumped into the thylacoid?
Water I’m pretty sure
the photolysis of water
when I become a doctor inshallah I'll send you money

Correction, photolysis is splitting of light. Hydrolysis is the splitting of water.
Light cannot be "split"... photolysis is the process wherein energy from light is used to split water. So, it is essentially just a special form of hydrolysis.
If all this would have been done by God, it would be much simpler....
