Photosynthesis: Light Reactions 1

I know I am so late on the discussion, but if all this were an accident, where does our value come from? In other words, if we are just an product of atoms dancing around, is human value just a social imagination?

I hardly can bear with the contradiction of our generation calling out for individual rights and value, where we simultaneously seem to be disgusted with the idea of a "life created with an intention."

Objectively speaking, evolution seems as nothing more than a speculation of overblown facts that have minimal similarity. (There's a DNA in a mitochondria! It must be an ancestor!) Our society calls out religion with "prove it with scientific evidence" but do you guys not realize there are more things that we do not know than we do know? Why are we fooling ourselves into believing that we know everything?

Science will explain what causes a phenomena, but never answer why it does in the first place. I hope you do not hold on so dearly as if it will rescue us from uncertainty of our existence.

As much as regarding religion and creationists as myths, the theory of evolution remains just as a myth as well. Let's not live and bring each other down like we have answers for everything.

I see so much beauty in this whole process. Even when we look at cellular respiration, breathing is not simple as we do on daily bases, huh? I just want to be amazed without self-disintegrating arguments that will die off like everything does under this sun.

If you insist on denying intellectual design, then please be consistent with your logic and deny your "not-yet-to-be-scientifically-proven-completely-but-it's-science" theory of evolution.

Thank you for reading. I believe that you really matter and deserve to be loved unconditionally, because you do exist in this tiny little dot in the unending spectrum of time.

I'm amazed of how much knowledge he has and how generous he is to share it with us. Bless him!

That's why khan academy is the best wuhoooo. Awesome

from which part of chlorophyll a es are excited ols tell

Seriously, thank you. You made it seem a lot easier.

Them electrons got me excited 😏💦

Thank you sooooooo much 🙌🙌🙌 why would I waste an hour trying to understand a convoluted chapter when I could come here for you to concisely sum it up in 20 minutes. I CAN NOT STRESS ENOUGH HOW MUCH YOU SAVED MY BIO GRADE!!!

Anyone here at 1am before a Bio test?

Thanks so much for explaining all the chemistry behind what goes on!!!!!!! So much more detailed than my biology book!

So I’m a middle schooler and I couldn’t study photosynthesis not because it’s complicated but I had questions and I felt the process was vague and I had multiple questions going on about it,I watched the photosynthesis series and I must say I understood and my confusion faded that might help too in upcoming years thank you khan!

Mind blowing explanation i never found such highly expertise teacher..
Thnkx a lot sir..
Now all doubts had been cleared..

Tysm life saver honestly

I love your channel thanks for making learning easy!🤗

i don't get why Hydrogen ion uses a complex to move across the membrane ,it already has a concentration gradient.can't it simply diffuse out?

Someone get this man a Nobel's price or something

bless you Sal Khan

How the hydrogen protons come outside lumen?

Sir thanks a lot for this video its been of great help good job👍👍👍

How does NADP+, electron and hydrogen proton make NADPH when the hydrogen proton is used in making ATP?
Does it mean that hydrogen photon is used in making both ATP and NADPH?

I'm sad that I descovered this a month before my university entrance exam, the way you teach is amazing that I would've given you my School fee🙏🙏🙏

Thank you sosososooo much

Man you were so happy about this being the only natural process where even water can get oxidized.

I remember watching your videos in high school to pass my biology tests. Now I'm here, after graduating college and working in biotech, still learning. Thank you!

any body here in 2021?

I love this narration. As the video goes on, the gravity of the absolute marvel nature and our environment really is can be heard in his voice. No matter how many times i listen to this process, I cannot believe the wonder of our planet.

Mr. Khan deserves Nobel Prize 💝💝💝💝💝

one granum two grana <3

I love you

Thanks alot!

No words BRILLIANT........❤
I Love Ur Videos.

Sorry I'm late for class... a moose wanted to wrestle, the moose tapped out, I was like "Yea, don't mess with me, I got to get to class."

Only one word for you sir...
Thank you very much 🙏🙏
God bless you 🙏🙏

Woah. that, is deep!! I Wonder how great are scientists.
And a 9th grader has to learn all this!😳

Find n

mmmmmmmmmmmmmmmmmmmmmmmmmmmm
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmnmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmnmnmmmmmmmmmmmmmmmmmmmmm

what ,that is SO COMPLICATED , this man knows everything

Feeling nostalgic listening to his voice

How Many Indians are Here?

good

i am watching it in 2022 is there any changes gone through... means the things which are taught in this video.

Thank you so much Sal! This is so amazing!

Literally
Literally
Literally 😂

I've been using your channel for A's since 2nd grade, keep up the good work, you're a life saver

This is so awesome thank you!!!

your the best

Ayooo

Please speak an urdu
