The question asks: Calc. the membrane potential from Goldman equation using pNa/pK = 0.02 & the conc. of Na & K inside & outside the cell. Calc. the membrane potential using pNa/pK = 20. Compare these calculated values of membrane potential with the numbers from the simulation. Why does the membrane potential shift when pNa/
A lab worker accidently spills a tray of slides you have just prepared of the length of the digestive tract, beginning with the esophagus and ending at the rectum.

Hi. Can someone please check my answers to the following multi-part question, and explain the questions I couldn't answer or that I got wrong? This is an 11-part question (!), but I think it looks worse than it is. It's 60% of a 1-hour test, so I don't think it should take more than an hour to go through, at most. For the
Monoclonal antibodies come from clones of B cells that produce a single antibody of known specificity. B cells will nor normally divide in the absence of antibody. The special trick that allowed monoclonal antibody-producing cells to be grown in culture was: (a) Mice were immunized with antigen and T cells removed and grown
Arnold, 67, visited his doctor for the first time in about ten years because he had noticed an increasing shortness of breath during gentle exercise. He has found this shortness of breath most noticeable whilst climbing stairs or walking up hills. Arnold had smoked one packet of cigarettes per day for about 50 years, but he re

Why is the distal tubule/collecting duct the only place to regulate osmolarity, seeing as we can absorb Na without H20 in the ascending loop? Is it just because the effect of any change in osmolarity earlier in the tubule gets undone (by ADH) in the distal tubule? Or is it because those earlier Na transporters aren't under physi
It is known that in ascites, liver damage usually causes a reduced osmotic pressure, and this results in edema. How does this increase the portal venous pressure?
