Title: osmolarity and Tonicity
Post by: portugal on 31/08/2007 00:32:15

1. Which ones would be hyper,hypo or isosmotic to red blood cells:
a)glucose (54g/L)
b)urea(1.8g/100ml)
C)Glycerol(5.52g/200ml)
D)sucrose(1.02g/10mL)
e)ethanol(0.069g/5mL)
F)distilled water

2. How can haemolysis be realted to the permeability of a red blood cell memebrane for hyper,hypo and isosmotic solutes??

3. What happens to red blood cells suspended in a solution containing 300 osm/L urea and 300 osm?L sucrose. explain in terms of solute movement across the cell membrane.

Not my field. But since to look at the layout of this question I think one might be justified in assuming you're looking for someone to do your homework for you (which we strongly discourage) I think you might choose to try google (or a textbook).
If I'm being unfair, perhaps you'd like to flesh out your question in terms of why you're interested in haemolysis... the people round here who tend to have answers to questions are mainly pretty busy so are more likely to answer questions that catch their interest.

Welcome to the forum, anyway. Whether or not anyone can answer your questions, there's a lot of interesting stuff discussed here.
