Title: Re: PhysioEx 8.0 Review Sheet Post by: Becky001 on Jan 30, 2011 Thank you Duddy!!!
Nnumber 5 is related wirh Simulating Active Transport , Could you help me with that, please. Title: Re: PhysioEx 8.0 Review Sheet Post by: duddy on Jan 30, 2011 5. The following refer to Activity 5: Simulating Active Transport.
With 1 mMATP added to the cell interior (left beaker) and the extracellular space (right beaker), was all of the Na moved into the extracellular space? Why or why not? No; ATP was depleted at 3 minutes. Describe the effect of decreasing the number of sodium-potassium pumps. The rate of active transport decreases. Describe how you were able to show that the movement of sodium was due to active transport. Sodium moved from the left beaker into the right beaker against its concentration gradient; there was no movement of sodium when there were no Na/K pumps added to the membrane. You will need to contribute more to the forum before I can help you any further with PhysioEx problems Title: Re: PhysioEx 8.0 Review Sheet Post by: Becky001 on Jan 30, 2011 Thanks,
I am new here, and I just found this great website!! Of course I will contribute with the forum Thanks again Duddy. :) Title: Re: PhysioEx 8.0 Review Sheet Post by: duddy on Jan 30, 2011 Thanks, I am new here, and I just found this great website!!

Title: Re: PhysioEx 8.0 Review Sheet Post by: nicole801 on Jun 12, 2011 This website is really helpful for my physiology class, thanks to all who have been asking questions and those who have been answering questions.
Title: Re: PhysioEx 8.0 Review Sheet Post by: arbase4 on Jun 15, 2011 Here is the first section:
Simple Diffusion The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). Which solute(s) were able to pass through the 20 MWCO membrane? NONE 1. According to your results, which solute had the highest molecular weight? Albumin 2. Which solute displayed the highest rate of diffusion through the 200 MWCO membrane? Na+Cl 3. Using the data from Chart 1, explain the relationship between the rate of diffusion and the size of the solute. The larger the solute the smaller the rate of diffusion Facilitated Diffusion The following refer to Activity 2: Simulating Facilitated Diffusion. 4. Did any of the substances travel against their concentration gradient? Explain why or why not. No, because in a facilitated diffusion substance can only move down their concentration gradient Title: Re: PhysioEx 8.0 Review Sheet Post by: patalt07 on Jun 17, 2011 Simple Diffusion
1. The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). Which solute(s) were able to pass through the 20 MWCO membrane? NONE According to your results, which solute had the highest molecular weight? ALBUMIN Which solute displayed the highest rate of diffusion through the 200 MWCO membrane? NA+CL Using the data from Chart 1, explain the relationship between the rate of diffusion and the size of the solute. THE LARGER THE SOLUTE THE SMALLER THE RATE OF DIFUSSION Title: Re: PhysioEx 8.0 Review Sheet Post by: angieq82 on Jul 18, 2011 Is it best to type out the exact questions we are having problems with along with the data we have collected or just the question that is causing the confusion?
Title: Re: PhysioEx 8.0 Review Sheet Post by: bio_man on Jul 18, 2011 Is it best to type out the exact questions we are having problems with along with the data we have collected or just the question that is causing the confusion? No, the exact question is always best. Title: Re: PhysioEx 8.0 Review Sheet Post by: kluly1 on Aug 4, 2011 im new to this site and am looking for help with the physioex exercises in particular filtration....can any one please help me
Using your results in chart 4, which MWCo membrane had the greatest filtration?............................. Explain the relationship between pore size and filtration?............... Which solute did not appear in the filtrate using any of the membranes?................ What is your prediction of the molecular weight of glucose compared to the other solutes in the solution?..... What happened when you increased the driving pressure?..... Explain why fluid flows from the capillaries of the kidney into the kidney tubules?...... And How do you think a decrease in blood pressure would affect filtration in the kidneys?......... Title: Re: PhysioEx 8.0 Review Sheet Post by: how_mendel on Aug 5, 2011 Is this solved?
Title: Re: PhysioEx 8.0 Review Sheet Post by: kennithparkson on Sep 8, 2011 What about ex 5b?
Title: Re: PhysioEx 8.0 Review Sheet Post by: duddy on Sep 8, 2011 What about ex 5b? This question is solved. Please create a new subject. Title: Re: PhysioEx 8.0 Review Sheet Post by: kla.valdivia on Sep 11, 2011 activity 2 pg 20
what occurs in the muscle during this apparent lack of activity? Title: Re: PhysioEx 8.0 Review Sheet Post by: riosmcdowell on Sep 11, 2011 I'm in H.P.A. Honors and this site helps me a lot thanks for all the contributors.

Title: Re: PhysioEx 8.0 Review Sheet Post by: jasminenikole on Feb 5, 2012 3. The following refer to Activity 3: Simulating Osmotic Pressure.
For NaCl, which MWCO membrane(s) provided for the net movement of water without movement of NaCl? 20 MWCO Explain how you determined this. (Hint: Correlate your results to the data in Chart 3.) Buildup of osmotic pressure due to the presence of non-diffusable NaCl in the solution causes water to diffuse down its concentration gradient. For glucose, which MWCO membrane(s) provided for the net movement of glucose without net movement of water? 200 MWCO Explain how you determined this. There was no buildup of osmotic pressure, which indicates that glucose is able to diffuse down its concentration gradient. Is osmotic pressure generated if solutes diffuse freely? No Explain how the solute concentration affects osmotic pressure. The higher the solute concentration, the higher the osmotic pressure.

Simple Diffusion 1. The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). • Which solute(s) were able to pass through the 20 MWCO membrane? None • According to your results, which solute had the highest molecular weight? Albumin • Which solute displayed the highest rate of diffusion through the 200 MWCO membrane? NaCl • Using the data from Chart 1, explain the relationship between the rate of diffusion and the size of the solute. The smaller the solute’s molecular weight, the faster it’s rate of diffusion will be. Facilitated Diffusion Title: Re: PhysioEx 8.0 Review Sheet Post by: Courtney134 on Sep 9, 2012 Thank you so much this was really helpful. :)
