Fractional Saturation of Hemoglobin

AI Thread Summary
The discussion focuses on calculating the fractional saturation of hemoglobin (YO2) at a venous O2 pressure of 30 torr, using a p50 value of 26 torr and a Hill constant of 3. The equation provided is YO2/(1-YO2) = (pO2/p50)^n, leading to the calculation of (30/26)^3 = 1.54. The user expresses frustration with isolating YO2 in the equation but ultimately resolves the problem. The final sentiment reflects relief after finding the solution. The thread highlights the challenges of mathematical problem-solving in biochemistry contexts.

Homework Statement



Calculate fractional saturation (YO2) for hemoglobin at venous O2 pressure (30 torr). Assume that p50 for hemoglobin is 26 torr, Hill constant is 3.



Homework Equations



YO2/1-YO2=(pO2/p50)^n

The Attempt at a Solution



(30/26)^3=1.54=(YO2/1-YO2)= 1.54 - 1.54YO2= YO2

This is pathetic. I am so mathematically retarded it hurts. How to solve for YO2...I can't seem to get it alone...why do they always play hard to get...grrr. Thanks for any help.

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
