Great teacher - She has so much enthusiasm and passion for this stuff. That's why it doesn't seem to get boring. I liked in particular how at 45:50 she dances like an enzyme ;-)
Thank you for mentioning Harry Noller (8:25) I helped rebuild his deck, and just meeting him and knowing what he had done gave me a needed reminder of how fascinating cellular biology is. I read a book called "Life Itself" in college , and loved what it explained; but it felt too late to pursue as a career. Having videos like this one to browse through when i want to feel awe is so nice. Thank you for your enthusiasm in teaching; and thank you TH-cam.
That's a good question. There is a hypothesis called "The RNA-world hypothesis." RNA can convey information AND be a catalyst. It's one of the things that Prof. Stubbe mentioned in an earlier lecture that, for example, a ribosome can function as a catalyst without any protein. Anyway, it's obvious that not all of the pathways came together at once.
This was great but I wish she talked about peptides. I thought enzymes help turn proteins into peptides. I'm trying to learn if it's possible to make peptides at home by combining specific enzymes with amino acids. Does anyone know if this is possible?
Peptides are amino acid residues peptide bonded together that form a chain of peptides called polypeptides, which are what proteins are composed of when of sufficient length. Enzymes are proteins with catalytic activity. They are a subclass. You cannot create a specific peptide sequence at your house from amino acids. The lab procedure is far too complex.
She’s wonderful, I love her enthusiasm. I wish my teacher was like this.
Yes true great Enthusiam
What a great lecturer! I could have done with this enthusiasm from my biochemistry professors.
Yes! She's brilliant.
@@ezequielxander9317 Just trust her instead
True
even though i want to leave the lecture but i feel i am disrespecting her in real. great lecturer and very detailed
I conquer with the rest, my understanding has been tripled .You are truly passionate and such a super smart lecturer

What a great lecturer! I wish this was my class
Your enthusiasm prof. is what amazes me. Great lecture delivery
To be Straight forward, JoAnne Stubbe is Sooo Personal To My Entire SCIENTIFIC CAREER 🙂❣️
great Proffesor, passionate and funny! love her
If all the Professors are like this, I will completely enroll remotely.
She's completely amazing
Its way difficult to get into MIT. Its not your choice😂
Fasih Naqvi I’m not MIT student
Amazing lecture and amazing professor!
:( MIT, what abput the other videos, like Enzyme Kinetics and Enzyme Inhibition, or Biochemical Transformations II, they are not
We try to ameliorate our scientific english
this professor is awesome!
Absolutely well done and definitely keep it up!!! 👍👍👍👍👍
An excellent communicator....
Is this what professors who love their jobs and are passionate about sharing their knowledge look like?
Amazing Mam. what a dedication
This is amazing!!! She is my hero.!
What an amazing class! Thanks a lot.
The board going up and down sounds like a sitcom laugh track
She's amazing wow!
That was great lecturer. She is so awesome
Stay blessed Mam salute your dedication
WHICH CLASS LECTURE WAS GOING ONAND WHERE .
THAT WAS AWESOME.
Invaluable class
Great lecture, thanks.
thanks teach...
Great lesson. Good teacher
thanks professor for this great lesson
Bless you professor!
really great lecturer! thanks
Simply amazing ❤️
How did biochemical pathways proceed before all these catalysts were present in cells?

thank you very much! 🤎
Amazing!!!!!thank you!
Only if I could get into MIT
the moment she wiped the blackboard gave me goose bumps :§
Please suggest any good book for enzymology in english.
Thanks
Learnt a few things about enzymes which are promiscous and are thirty per cent metals!
Awesome!
45:42 :D
hahah very awesome
She was an expert break dancer back in her day.
She did the "Dance of the Enzymes"
@9:59 Haha, I love her!
Now, I really make a connection of how fast and important enzymes are to a reaction!😀🥰
only one thing that concers me - I won't talk about this at all!"
Make it short
Where can I get her lecture note?
Free course materials are available at MIT OpenCourseWare at: ocw.mit.edu/5-07SCF13. Best wishes on your studies!
as my professor said "there's enzymes for that" 😁
That chalk got my all teeath 🥴💀
