Unformatted text preview: 99 mol in each compartment. Hence: 180 g Mannose
0.099 mol ×
= 17.982 g of Mannose 1 mol B. If the effective resistance to flow across the membrane is 83.5 kPa s/mL, what is the flow rate of water across the membrane during steady state (in mL/s)? (10) ΔP
Solution: Remember that flow rate as a function of resistance is given by Q =
. You R
were provided the osmotic pressure gradient (i.e. pressure difference) in part A. The resistance is also provided. Hence, solving for flow: ΔP
167 kPa
Q=
=
R 83.5 kPas mL mL
Q=2
s QUESTION 2 Consider a newly discovered microorganism and the transport of hypothetical ions A+, B2+, C , D . The table below lists the intracellular and extracellular concentration of each ion as well as each ion’s relative conductance. The temperature is 37°C. (20 total) A. Calculate the values of the equilibrium potential for A+ and B2+ (in mV) (10): Solution: To calculate equilibrium potentials for indivi...
