Solved in 2 steps
- How are these two factors of the concentration gradient and the equilibrium potential mathematically related?List the two forces that make up the electrochemical gradient may in some cases oppose each other?Is there a way to predict how much electrical force is required to exactly balance the tendency of an ion to diffuse down its concentration gradient?
- what is an electro gradientwhat does the term excitation- coupling mean?If: membrane potential=-70mV, ENa=+60mV, and Ex=-90mV, consider which directions Na+ and K+ will leak across the membrane. If both ions are crossing the membrane, what is the most important factor in determining whether membrane potential will become more positive or more negative?
- If the equilibrium potential for K* is -90mV, and the charge inside the cell is -70mV, which direction will K move across the membrane assuming there is permeability (membrane leak channels) which allow it to pass?What is hypotonic solution ? Write effects of hypotonic solution.V=62 log 10 (C0/Ci ) for a positive ion at 37 degrees Celsius. What is theoretical ratio of solution ion across the membrane when the resting membrane potential is 124 mV?
