simplification

Postby twistedesoterix on Tue Mar 04, 2014 7:46 am

So, I haven't had algebra in 2 years and I'm stuck. I need to simplify this whole mess. This is actually from my Enzyme Kinetics class but I'm stuck with the algebra...

v0={(Vmax*[S])/(Km+[S])}/{(Vmax*[S])/(Km(1+([I]/KI))+[S])}

I got as far as...
v0= {(Km(1+([I]/KI))+[S])} / (Km+[S])

After that, I don't know what to do. Any help would be much appreciated...

Thank you in advance...

Before we proceed, are the above correctly converted below into "mathiness"?

(If so, then you've done the first step correctly.) Thank you! :wink:

Yes, that's correct! I'm new & I was typing that on my iPad. Thank you. What do I do after that? How can I further simplify this?

I think you can do out the fraction but that's about it.



Nothing factors so nothing cancels. You could maybe rearrange but that probably won't be "simplifying":

Your last equation! That's what I needed to get to. Thank you so much! My book explained how to get the ratio and the last equation but didn't explain how to get there (since it's not a math class).

Thank you sooo much!!!
