I am a second year med student reviewing this for boards (70k/year debt, woo!). I spent many hours attempting to learn this in my first year, but I never truly understood it beyond "free nitrogen is bad, urea is good... now memorize all these random chemicals to make urea...". I literally wasted hours of my life memorizing/purging this for exams, and now, in 13 minutes, you actually TAUGHT it to me such that I UNDERSTAND what the heck is going on. You have an incredible gift... Please never stop teaching. Thank you so much for this! Best of luck with your future endeavors.
You never cease to amaze me. Countless hours of studying cut to min. because you are a pro at organizing information and conveying it. THANK YOU! The few thumbs downs are probably from jealous profs. You kick ass.
Hey, I told all my friends about you! And even now when I'm no longer studying biochemistry but focusing on Internal Medicine I'm still getting back to you to remember the basics. So thank you so much. I will never forget your help. 😭♥️
Bro I am pharmacy student and believe me you are the reason i cleared my all the semesters and i can stand confident in front of my lecturer that even wirhout listening to there lectures i can clear the exam.. thank u very muchh..
I had biochemistry structure final exam today and I hadn't studied anything because I was so sick! So I woke up very early in the morning and started watching your lectures that were related to my exam! I'm just going to say that you are amazing because not only I'm going to pass but I also was able to answer some tricky questions because of the details you mention in your lectures! Thank you very much, god bless you!
Thank you SO much for all your hard work and putting together this videos! You've helped me pass all my biochemistry classes in the University. You are so good at explaining everything. Love that everything is visual and color coded. You are amazing!!!!!!!!!!!!!
thank you so much sir !! I was studying this from Lippincott but everything was just passing over my head. now after listening to your lecture everything is crystal clear! you provide every detail necessary for tests and your illustrations are also so perfect.
I would just like to let you know that you are a saint. One day when I have money I will be donating because you have saved me from failing my biochem courses. You deserve the world
Shout out to my guy AK Lectures, man jeez! My biochem professor is good, but I never have time to go to her office hours with work and everything. This dude is literally my personal TA.
Amazing I should really show your videos to my lecturer so he would learn how to teach better, I went to a 2 hour lecture today and didn’t learn anything, great work!
Sir, your lactures are full of important information and very much interesting and beneficial for us. I believe you are one of the best biochemistry teacher. Thank you Sir for such help 🙏🙏
Thank you so much! You have helped me many times in my biochemistry exam! Actually, you helped me aced it. Thank you for organizing a comprehensive summary of topics like this one.
He mentioned that the change in free energy obtained from breaking the bond in a pyrophosphate (PPi) is equivalent to breaking a single phosphate from ATP, so in step 3 the energy used to drive the reaction is effectively equivalent to the lysis of 2 ATP molecules
There is one minor issue: inorganic pyrophosphate is quite stable at neutral pH and requires action of inorganic pyrophosphatase to convert it to two phosphates. Which is what happens. Without the action of inorganic pyrophosphatase, PPi would accumulate and inhibit many nucleotidyl transfer reactions, including those in nucleic acid synthesis. So 3 ATPs is what you need on the left-hand side of the urea cycle equation, not 4.

probably from jealous professors :,)))) lmao
Can you tell me why you can summarize this for free + 100x better than my med school professors who I pay 50k per year?
right?!... this guy is the reason i might do alright on my boards lol
they give u a certificate
he explains this better 47932875982x better than my undergrad professors too 😂
Can't agree more bro
Every time I watch his videos have the same question as yours🤦🏻♀️ I’m really curious but however the reason I am always thankful for him
man you are really an amazing lecturer, half of my good grades are because of your lectures. thank you for putting all these up.
seriously who would ever unlike this video !! U R world's greatest lecturer
thank u so much !
How did he get the urea cycle drawn in a perfect circle diagram? he is too good.

@@faisalal-sammarraie9140 Did not use a compass.
@@AKLECTURES cool omg
A marker and a string?
Taking my Biochemistry exams tomorrow: if all goes well. After God, all the credits goes to you.
Abdimutaal Miyir Thanks to God who created him

I wish i have money to give to this guy
Christian Mark Gerard Tuvera don't worry he's getting paid
Hannah Lopez I am actually not getting paid
@@AKLECTURES thanks a lot then!!
Same. Let me graduate and make a living. then for sure :)
@@AKLECTURES Omg, Incredible, you are amazing!
Bro I am pharmacy student and believe me you are the reason i cleared my all the semesters and i can stand confident in front of my lecturer that even wirhout listening to there lectures i can clear the exam.. thank u very muchh..
there can never be an easier way to learn after watching ur lectures.
I have a big test tomorrow and I am so thankful I found your videos! They are the best tool EVER!! please keep up the good work!!!

Ur explanation is awesome
I can't help commenting this on every video I watch on this channel ..... THANK YOUUUU!!!!!! :)))))
Thank god for your brilliantly condensed and fastidiously distilled videos. I'm illuminated.
the best lecture TH-camr ever
learnt more in these 13 minutes for free than 2 hours in a lecture for thousands a semester..... THANK YOU FOR THIS!
Trully gifted. Few understand this material in such depth and even fewer are able to explain it properly. Keep up the great work!
I would just like to let you know that you are a saint. One day when I have money I will be donating because you have saved me from failing my biochem courses. You deserve the world
Watching this video a day before exam..totally life saver! Thanks Sir! 🙏
you are my hero! thank you for helping me through med school
I’ve never seen a better explanation. Thank u
Thank you so much for making these videos, you are getting me through my biomed degree!! So grateful
You got me through my biochem exam. Thank you so much. You are godsend
literally no one can explain this way better than you do🙌🙌🙌
I just covered this in an hour. And I couldn't get it thru the whole year😂thank you
Doctor, you’re so good in how to artistically put things together. Well wishes and many thanks.
Shout out to my guy AK Lectures, man jeez! My biochem professor is good, but I never have time to go to her office hours with work and everything. This dude is literally my personal TA.
Ohh my god! You're just amazing. I was looking for this so long and finally found this video. Man! you made it CRYSTAL CLEARED!
always grateful for your videos! thank you
thanks for the kind words!
I JUST CAN'T THANK YOU ENOUGH
Hi babe
Your videos are great! They have been of great help to me. It makes understanding and learning so convenient.
Amazing I should really show your videos to my lecturer so he would learn how to teach better, I went to a 2 hour lecture today and didn’t learn anything, great work!
He really give us all the knowledge he has acquired for god knows how long for free.
I love this person's teaching like anything
you are the best teacher ever !!!!! thank you so much
I liked it when you spoke loudly in the mic and had a cool accent. This is too peaceful, bring the 2017 voice back
This guy is simply brilliant. Thank you very much. I wonder why the 33 guys disliked this video. Shame on them
Your videos are amazing! I'm definitely donating. It's worth the $$. Thank you!
U r great 😃 أنا فى كلية العلوم من مصر

Thanks sooo much..much love from Nigeria ♥️♥️
thanks I dont understand this cycle but by you understand this cycle thanks a lot
At 9:55 you mention you used two not one ATP molecules for step 3, could you elaborate on that? Why are you saying 2 were used?
He mentioned that the change in free energy obtained from breaking the bond in a pyrophosphate (PPi) is equivalent to breaking a single phosphate from ATP, so in step 3 the energy used to drive the reaction is effectively equivalent to the lysis of 2 ATP molecules
Sir
Hats off to you, for such a beutifuly simplified Presentation

Youo have really impressed me. I can't hide it!
God bless you ✨ well Explained

Inorganic pyrophosphatase is not an ATP-dependent enzyme, by the way.
Thanks brother... You explained it nicely..
Great job!
Sir you are so inteligent, love from pakistan
Wonderful explain!! 👌
Superb video as always... thank you so much!!!!
