- Let's explore what enzymes are, and how they can affect a reaction. The most important affect you need to know is its ability to "catalyze" the reaction. By Ross Firestone.Created by Ross Firestone.

I would like to write in my certificate, GRADUATED FROM KHANACADEMEY UNIVERSITY !
great job !
Congratulations
I have an interview to secure a good scholarship in about 5 days and these videos are helping me a lot. Thanks!
thank you #khanacademy . I past my exam of biochemistry ... u r the best
Really nice video
i like to see more of this guy
i like his explanation
Great video! learned so much!
This is gold!! Super easy to understand. Thank you!!
I stand corrected, thanks Leslie.
Looooved the example you gave, Mr Firestone!
So far still mostly over my head, but nevertheless a very instructive video. I now understand a little more. Thank you.
Thank you!
thanks for the clear explanation. helps me a lot. thanks khan academy!!!
omg! you are so helpful!!!!!!
Thank you
Such a helpful video!! Love the animations....helps me a lot since I'm a visual learner!
amoeba sisters
Unbelievably useful videos about enzymes, thank you Ross!)))
Give an individual video on Proximity & orientation.
My university life without Khan Academy is lifeless!!! GREEAAATTTTT VIDEEEOOO
nice
With 1.5 speed I learned more in less than 5 minutes than I did in school
nice explanation dude, cant wait to right ma exam to see how effective it is
where is the video on keto-enol tautomerization ?
Biochem is killing me right now talking about catalytic efficiency and enzyme kinetics. I come here all the time to stay primed before I go back and fuck my brain again in my textbook. Thanks!
our biochem class taught us enzymes themselves never speed up a reaction but instead increase rate of reaction by LOWERING activation energy (Ea).... is that wrong based of this video?
=
Enzymes do indeed speed up a reaction, and it does this by lowering activation energy, via a mechanism such as those described in this video. What the enzyme does not do is change the total free energy difference, so that may be what you were thinking of.
What happened to the O- on the molecule on the left?
Ok that does not look like a soda...
Me: "I want to be a surgeon one day."
Me: *Is doing biotechnology stuff in high school wondering how on earth I will get accepted into a pre-med program with biotechnology*
correct me if I'm wrong, but didn't we want an enzyme -- not an ion -- that uses hydrostatic strategy for catalyzing a reaction? dna polymerase doesn't use h.static interactions to speed up anything. the ion, Mg2+, is the thing enabling the enzyme dna polymerase to work.
seems like we were looking for enzyme variablename that brought Mg2+ ions to speed up the rxn of pairing nucleotides.
Why am I watching ochem vids for fun haha
Lol
This made no sense at all............
Maybe becuz I'm not old enough
