Photosynthesis Part 3: Photophosphorylation

[@Rebel8363]

Gosh, Craig, I love you so much for making this video. It's a golden mine. Thank you!

[@romellopes2022]

the best video,...liked it so much !!

[@susanbennett3409]

Fabulous explanations of the underlying mechanisms of life! I love all your videos!

[@glitterlicious01]

Thank you this is the third video I watched from your channel. I'm learning a lot.

[@maui7569]

great form of delivery this made it crystal clear

[@ndlovukazim318]

Your explanations are amazing!! You are a great teacher. Thank you

[@alexiscornwell22]

man, that voice is angelical

[@cococrunchize]

please be my lecturer already..i promise you i'll get distinction for the subjects you taught me.. ahh best explaination ever! great job!

[@gokharol]

You couldnt make it any better! This is perfect!

[@IPSPMAN90]

Thanks again! You are doing so great when explaining such concepts and make it look simpler than it is :) Keep doing such a great work, without thee videos I wouldn't get these stuff so fast and actually learn it and understand it :)

[@MichaelHarrisIreland]

Absolutely great videos. I keep thinking it might not all add up and then the happy ending as H+ pops up again to save the day.

[@KKan90]

This is the most.. I mean.. so touching me... your series of videos are so easy to understand and helping me (i'm sure not only me) SSSOOO much... Thank you for your So hardd work and please keep post these helpful videos....!!! >< THANK YOU !!

[@CraigSavageScience]

It is a very good question. The answer is that it actually picks up "2" electrons and "1" proton to "reduce" NAPD+. One elctron and one proton = the "H" (hydrogen) and the other electron reduces the postive charge to nuetral.

[@MistahJay93]

Amazing explanations honestly! Really helpful for those trying to learn biology, the animations really make the learning experience FUN =D Thank youu very much!

[@sweetwa089]

wow such scientific observation

[@charmkk9448]

YOU ARE THE BEST... THANK YOU FOR THIS VIDEO!!!!

[@yushiliang1]

Beautiful! Absolutely one of my favorites. I already subscribed to you I think.

[@divyacrotu7061]

From where the H+ used in proton pump to help the electron pass through the ETC comes?

[@ull893]

Great question and answer. The same question which always confused me. Then I thought, it might pick up only one electron and it might get shared between NADP+ and H+, like in a covalent bond. Now, I know I was wrong. Thank you.

[@deepanshudhaneshry8638]

best explanation ever

[@PartiallyDeveloped]

Hydrogen is not used directly to form ATP, the energy of the gradient is utilized to bind the inorganic phosphate (Pi) to the ADP. The hydrogen that leaves the cycle is the one which is used to reduce NAPD+. This hydrogen comes from photolysis, and so as long as water is present to be split, there will be a hydrogen for this purpose. In short, so long as water is present, there will be a supply of hydrogen ions to feed those which leave the cycle.

[@10Alan17]

Don't the highly charged electrons in PS2 get accepted into pheophytin before Pq? and from what I could tell from your animation it looks like Pq is hydrophobic and Pc is hydrophilic. Thanks your videos are helping a lot

[@gmsdayounger]

man how do you do it,,,,great mine...finally i got the topic

[@CraigSavageScience]

glyceraldehyde 3-phosphate = PGAL (phospho-glyceraldehyde) (same thing different naming system) Two of these three carbon molecules are converted into a 6-carbon sugar (Glucose).

[@arushizutshi1051]

from where is the H+ ion coming into the thylakoid space from the stroma(electron pump)??

[@SuperKnowledgeSponge]

If the ETC provides the proton pumps the energy required to pump H+ ions into the matrix from the outer compartment, where does the H+ ions from the outer compartment come about? How are H+ ions formed?

[@drumandball]

What is the name of the second electron carrier after the excited electron moves down the first ETC?

[@kaitlynhill1545]

[@mohammadhasan4253]

Nice Sir

[@AmiriTheGrey]

Dude, you helped me so much, thank you!

[@pattfy]

I love your videos! :)

[@williampaz8240]

Does the H+ to make NADPH comes from the lumen? Or it's a H+ from the stroma?

[@williampaz8240]

NVM I saw the answer lol

[@lolibrigade]

WHY does the NADP+ need BOTH a proton AND an electron to be reduced to NADPH?? why can't it just use either/or?

[@gokharol]

Is water broke inside the thylakoid or strome?

[@qamariqbalawan7823]

where does p with ADP come from??

[@camiecamper]

ikr i'm taking the same exam these videos really calm me down XD

[@AB-ht7xk]

plz upload other topics of biology also

[@nepaliguy6537]

BEST VID OUT TYYYY

[@aleksandarnikolic9005]

Where are those protons pumped into thylakoid space coming from ? H2O and photolysis?

[@spearhead7524]

Stroma

[@TT-qn2rw]

Where does NADP+ come from?

[@Arrakis626]

your videos are kind of boring, but they're very helpful, so thank you for posting them. :)

[@christinah.181]

that was and is sooo helpful, thank you! :)

[@saraabdullah1420]

Thank u so much, this was very helpful :)

[@1800YueeWish]

In my biology book for college, it says that the end result is glyceraldehyde 3-phosphate

[@TheArindamusician]

very comprehensive

[@1800YueeWish]

Thank You!

[@MMM-np4oo]

👍👍

[@cindyla2902]

Thank you so much

[@salima-3]

جيد

[@SuperKnowledgeSponge]

sorry not matrix, from the stroma into the lumen of the thylakoid/granum

[@phineasjosipani8516]

hi good ****

[@Omgwalrus1]

This was helpful but could've been a lot better.. the huge amount of "this is what happens.. but also not really i'll tell you later" in all these parts really screws revision wen you're trying to get all of photosynthesis practically memorised, you ruin the chronology of it for no real reason

[@minervadulnuan5669]

Then probably, why not make your own version of the photosynthesis process in chronological order and perhaps in a better way for others also to understand it better. :-) Have a great day!

[@YouThinkDeeper]

damn,im again at weird side of youtube...

[@scribblerofdreams]

+aiwa juo some of us learn this for school. it isnt weird...

[@brandonsandoval7290]

At about 2:50 he implies that cyclic photophosphorylation uses photosystem II, when in fact it only uses photosystem !. Think about it. Nice video otherwise.

[@opensourcecurrency]

Slow down and speak more clearly...but thanks.

[@TheFrollein]

Can you please do some dirty talk in between... perfect voice

[@VictoriaRittenhouse]

Thank you!
