Equilibrium potential is assessed. - When the internal sodium concentration is set to equal the external concentration the equilibrium potential went to zero. Why? Details are presented.
Goldman equation is explored. - 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 th ...
A two electron transfer reaction you are studying has a standard state standard reduction potential (Eo') on 0.137V at 37C. - A two electron transfer reaction you are studying has a standard state standard reduction potential (Eo') on 0.137V at 37C. What is the equilibrium constant for the reaction (Keq') at 37C?
Diffusion & Osmosis - Can you help me out with these problems (see attachment)?
Concentration/Dilutions - There is 100 mg of protein dissolved in 100 mL water. Then 10 microliters of that solution is dissolved in 990 microliters of water for total volume of 1.0 mL. To calculate the concentration of protei ...
