According to Khan Academy, the MCAT courses will be retired on September 30, 2021. I've really enjoyed watching the videos in this series because I am learning a ton! Will this series remain on TH-cam?
In the last part of the strecker synthesis, you have NH3(+) attached to the carbon. Shouldn't you also have a negative charge on the carboxylic acid where the carboxyl group is to be CO2(-)?
no, this is organic synthesis of amino acids in a lab setting with chemical reagents. The ribosome makes peptides from amino acids that are consumed through digestion (9 of them are the ones that you eat) 11 of them your body can make from the side products of metabolic pathways. Then peptides are made and a bunch of peptides make up a proteins all of this happens in the ribosome
@Hemlock Cocktail They've stripped them from plant and animal proteins. Combined them in a test tube. 100,000+ not one protein formed. Energy is needed, a catalyst made of proteins and a metal ion to pop them together. And specific proteins are made of combinations of the 20 different amino acids, coded by rna to ribosomes which are made of proteins that assemble them according to instructions delivered by the rna, trna, mrna's. You have no idea how perfectly ignorant your assertion is.
@Hemlock Cocktail How is a closed glass apparatus with a trap to preserve the intended products. (Results were worse without the trap)Limited to specific elements, a continuous spark and a "trap" spontaneous? 23 amino acids were detected in piddly amounts. 10 relevant, 2 possible residues. All 50/50 right and left handed making half worthless of the total 2% found dispersed in the tarry gunk from the trap. How do individual amino acids manage to be located anywhere near other relevant amino acids in a sea of molecules to polymerize? Swim? Much less, with only, at most, 12 of the 20 needed to form proteins. Who are you to be calling anyone stupid? Psalm 139:14 I will praise You Lord, for I am fearfully and wonderfully made, and my soul knows this very well. Marvelous are Your works..
+Rawan Dh I don't mind it but the way she finishes most of the sentences by doing some weird stuff with her throat is really distracting xD I can't stop imitating her
This makes the the reaction so much easier to understand, thank you!
i have been struggling to understand this for the MCAT until watching this video, thank you very much!

It would have been so much more helpful with arrows to represent the movement of electrons.
Will it be really this simple on the MCAT?
thad was a good video
Thanks for easy tutorial. Please add English sub title every vedio.

She went through this way too fast. These are somewhat complex reactions that aren't overly intuitive.
Very Helpful! Thank you :)
Does this happen in the ribosomes?

Great thanks.
Your voice so sweet and lovely
Could this take place in any warm pond, murky with chemicals and struck by lightning?
I understood that reference 😹

@Hemlock Cocktail How about Romans 1:18-22 describing your futile delusions..
@Hemlock Cocktail You've been advised.
I love u pakiza mam
صوتها مزعج 🙂
मराठी त बोल यात काही समजतं नाही 👌👌🚩
I don't like the way she talks... very fake!

I don't like this lady. Always rushes over topics and though simplifying things is good but not too much.
+Laila Samadi she's supposed to give you the backbone, then you're supposed to fill in the details from the reading material
There is reading material? Where?
Laila Samadi
well your college course or wikipedia
inine?
