What happened to the slow, thorough videos by Sal? Not a fan of this kind of video.

what is the point of the dbl dagger on delta g?
Jorge Rivas (2 года назад)
It is a pity that the speed of your voice goes so fast, because the information is very good formulated
Yumna Maheen (1 месяц назад)
You can slow down the video using playback speed
Secret Moon (2 года назад)
you can turn on the subtitle (the CC button at the lower right corner of the video)
Lesley Flores (2 года назад)
Jorge Rivas I agree, I downloaded the app and was able to slow it down though
Ines Lep (2 года назад)
I'm just so, so glad I found these videos. It helps so much!

slow down please...

Done as assignment on this in biochem in my first year. Although my grade was ok I didn't enjoy that assignment in the slightest. Lecturers have a habit of presuming a certain amount of background knowledge from students and often don't explain things in a comprehensive way. This video would've helped me understand my assignment a bit more. Its one thing learning/remembering information, but understanding something is often more important than recollection.

These kinetic video's are so helpful and sums up what my lecture was dragging out for about 2 weeks very nicely. Many thanks!

Enzymes do not affect delta G, because delta G tells us whether or not a reaction is spontaneous. The enzymes only catalyze a reaction which is already spontaneous. What you meant was probably Ea (activation energy).
The Archivist (1 месяц назад)
He never said delta G is changed. He said energy of activation (Delta G cross) is changed.
MD P (2 года назад)
What he meant was lowering the delta G of the TRANSITION STATE, which is, indeed as you said, the activation energy (he did say the activation energy in the video)
FourTwentyMagic (2 года назад)
Activation energy is a change in enthalpy or Gibbs free energy if you will.

+Ryan McNamee http://www2.fiu.edu/~cuervol/cellphysiology/enzymes/enzymes.htm maybe this helps clarify what I meant
Ryan McNamee (4 года назад)
You can plot delta G or delta H. It still gives you an over all energy difference and barrier.

Can you slow down a bit? You seem to be rushing and it's hard to grasp what you're saying.

LOL i am watching the video @ 2 exam tmrw
