Human Physiology Lab X1 Questions Question 1 4 Points PEX-01-01. Select the smallest MWCO (molecular weight cut off) membrane that the solute would be able to pass through successfully. Na+/Cl- → 20 Urea → 100 Albumin → none Glucose → 200 Question 2 6 points PEX-01-01. Based on your results, order the solutes from smallest to largest molecular weight 1. Albumin → largest 2. Glucose → Glucose 3. Na/Cl → Smallest 4. Urea → 3rd Largest Question 3 6 Points PEX-01- 01. Select the closest match for the average diffusion rate (mM/sec) for each solute with the MWCO membrane you identified for that solute in question 1, with a starting solute concentration of 9mM in the left beaker. 1. Na+/Cl- → .0150 2. Urea → .0094 3. Albumin → no diffusion 4. Glucose → .0042 Question 4 6 Points PEX-01- 01. Examine the results you recorded for different solutes and a concentration of 9mM in the left beaker and deionized water in the right beaker. Which of the following is responsible for the difference in diffusion rate when different solutes pass through the membrane? 1. Molecular weight and size Question 5 6 Points PEX-01-01. Enter the time it took for the experiment to reach equilibrium for each of the following solutes and concentrations. NOTE: YOUR ANSWER MUST BE NUMERIC. DO NOT INCLUDE ANY TEXT. If the answer was 5 minutes enter 5 NOT 5. Or 5.0, etc.
