Integral proteins
Note: This is not a homework question. I am just trying to understand the mechanism of integral proteins. Question: We know integral proteins have nonpolar regions inside. But are integral proteins like channels (which have a tunnel inside) or are they like pumps or are they not hollow and cannot pa...

Re: a SUPER DUPER DIFFICULT QUESTION!!!! PLEASE HELP!!!!!!
Thanks!!! 
But could you cite exactly what about those topics that would help me?
I mean, I read over http://en.wikipedia.org/wiki/Brownian_motion and it seemed to me more like math and equations that the mechanism of negative pressure.
Please help! Your insight is greatly appreciated.

THANKS! So let me clarify: Question: why does gas flow from a region of higher pressure to a region of lower pressure - WHAT IS ITS MECHANISM?????? Answer: This is the same mechanism as diffusion (as gas molecules move much faster than water molecules). Question: My book says that a FLUID (MEANING E...

sorry. you were right. I will now try to make it a little more clear. There is a main question (bold) and then a side question (italized). I'm not sure where this question should go, as there is some chemistry involved. But I saw this concept in my biology book, so I placed my super hard question he...

enzyme question
NOTE: This is not a homework question. This is a study effort for a big upcoming test.
Can enzymes use energy (like ATP) in powering their reactions? How do they catalyze reactions if they don't actively use energy like ATP??????
