hi, Sorry, I really thought I put this in the Hw section under the sciences...

Mg 2+ (aq) +2 OH- (aq)= Mg (OH)2 (s) If I measure pH of springs near Jenner to be pH=9.5, what can you tell about the equilibrium activity (concentration) of magnesium in that solution? You need to calculate the dissociation constant of water. Not sure how to start this? Any help

ok yea that makes sense. Like I have 3 micromolar instead of 3 X10^-6. Like I just thought it would be easier to plot the values without all the extra zeros

at epenguin, yea it was my math that was wrong. It turns out that the answer was 6. :)

at ieatpasta: Lol, yup, mcb 123 with Wilson? I don't know how much of help I would be to you because honestly, I am like sooooooo lost in this class... On a more serious note: I checked my math and I got 6 binding sites too. But i think you have to look at your units again. I think it's 3...

Thank you for clearing up the units for me. Now I got a linear regression line that actually makes sense. Our professor told us in picture that he put one micromolar of protein so I'm guessing that's the E total I need to solve for the number of binding sites?...anyways, when i solved that i...

Yea, I don't have a scanner with me now...actually the assignment is in pdf format. I don't know if that makes a difference? But yea...E24 mean 10^24... I'm confused if I'm doing unit conversions wrong? But I think our professor wants the x-axis in molar and the y-axis shouldn't have...

Hi, I'm having trouble plotting this data Is there a way to attach the homework assignment so that you guys can view it? Anyways, I'll type it for now: We need to determine the dissociation constant for L (ligand) and the number of L binding sites on P using a scatchard plot...

Hi, Sorry for not thanking you earlier lol. But I think got the slope replot thing down.

hi, My instructor has given us an assignment where we have to diagnose the type of enzyme inhibition it is. I diagnosed it as a competitive inhibitor and am trying to do a slope replot to find my value for KI. For the slope replot, you just find the slope of the each line? is it the same...

Hi, I have an assignment where we basically have to make a Velocity vs. Substrate plot and find the Km and Vmax values. We then have to do a double reciprocal plot and find the Km and Vmax from that. My first question is if I have to convert the units of my axes so they are uniform...
