Question

Need help with 21- but all answers would be appreciated to check my work.

Use the scenario and figure below to answer questions 19-21 Below is a depiction of a portion of the cell membrane that is positively charged on the intracellular side and negatively charged on the extracellular side. Further, in this cell the concentration of ion X* in the intracellular space is high and in the extracellular space is low TY-]high extraccUular [X+]low Y-low 19) Does an electrical or chemical gradient exist for X"? If so, what direction is the gradient? (3 points) MATCHING OPTION: one exists * inward * outward, a) electrical gradient b) chemical gradient 20) Does an electrical or chemical gradient exist for Y ? If so, what direction is the gradient? (3 points) MATCHING OPTION: one exists * inward * outward, a) electrical gradient b) chemical gradient 21) Would you predict the equilibrium potential for X* is a positive or negative value? What about for Y? (4 points) MATCHING OPTION: * positive membrane potential * vegative membrane potential epa * Unable to determine from information provided membrane potential a) Equilibrium potential for X*: b) Equilibrium potential for Y:
