Photorespiration

[@majesticpegasus]

for those in a hurry, he starts explaining the actual photorespiration at 5:16

[@tobytobtob7450]

Thank you so much

[@zaraa5104]

thank you! ♥️♥️

[@Geeth88054]

Tnx

Sal, like an idiot, I went to other videos first. Between their potato cameras, the lack of ANY charisma, and my general disinterest, I was ready to just throw in the towel and realize I couldn't care less about plant metabolism if it were telecast on CSPAN. Then I remembered my academic blankey, KA. Thanks, KA for reviving me and sheltering me under your safe, warm wings.

[@davidheatherly171]

Right.

[@aunmaqsood3129]

lmao nice

[@HK_ASTORIA]

I don't know who this guys is but he is awesome. I love watching your videos!! you always explain things in such a fun, engaging and a thorough manner. LOVE it. Thank you!! :)

[@herrsteppsch29]

just passd my Biology exams!
I used ur Video to study! thanks!
greetings Form germany!

[@kent9384]

schreibe mein bio abi nächsten montag. hoffentlich kann ich dann das gleiche sagen!

[@herrsteppsch29]

@@kent9384 lol. Das waren noch Zeiten. Viel Erfolg!

[@kent9384]

Herr Steppsch Vielen Dank!

[@themadladprince430]

This man teaches everything

[@nadeeshaperera7923]

Thanks.. It was so easy to understand

[@sarabegum5437]

Sir why an fundraiser channel you should get some profit you really work hard

[@davidheatherly171]

Very well said. Thank you all.sincerely, Dave16.

[@SoulReviving786]

Sal khan you are the best best ..
Your academy is best ..
And your staff efforts and competency is worth appreciating ..
I wished if we were also having competent staff like this in our school and colleges

[@ScenerySpace96]

easily understandable video

[@demonrhythms8761]

thanks for clear english without traditional indian accent

[@mutahiranaz836]

What is wrong with Indian accent?

[@DasuniPerera-k6j]

Thank you so much ! 💐💐

[@saunyboy123]

NADPH, ATP and NH3 are also uselessly wasted in photorespiration

[@nitinTDM]

Thanks🖤

Thank you

Isn't this just a way for plant to guarantee to get CO2, even when it doesn't get it from air outside. Or where does those CO2 molecyls go?

[@shraddhakharole3631]

Did you get an answer to it?? Becoz I have the same question!

[@Quackadillyblip27]

In this process Co2 is generated at the cost of RuBP not being regenerated, therefore the CO2 produced can not be fixed in the Calvin cycle.( Since the Calvin cycle requires RuBP )
So the co2 produced really has no use which is why I highly doubt that this mechanism is a way to gaurantee co2 for photosynthesis and is more of an evolutionary fault.

[@aaaaaa-hh8cq]

the answer is no.

[@ncdave4life]

Good lecture! How do you do the writing? Are you using a Smart Board, or a tablet of some sort?

[@saswatighosh3812]

probably a small board with a light pen....i have used those for signing digitally

[@alex_zetsu]

Looks like photorespiration only happens in significant amounts when the stomata are closed. If they are closed, then the 3 carbon dioxide atoms lost to this process don't have anywhere else to go. So they will probably be reabsorbed in the normal Calvin-Benson cycle.

[@hamedhosseini4938]

I love you Sal

[@jettburns8879]

I noticed that Sal wrote Rubisco's name as RuBP oxygenase-carboxylase. However, I learned in one of his previous videos that Rubisco is short for RuBP carboxylase-oxygenase (hence the acronym). Pointing out that detail, great video otherwise!

[@malik.hammad]

What is the name of this teacher?

[@hemlata5610]

Bt what's d benefit of photorespiration

[@lolamoon7296]

It’s helpful to complete photosynthesis when the area is too hot for the stomata to open and it only has access to o2

[@shekufeMokhtar]

it's soooo perfect
