Changes in Ion Conductance or Ion Concentration Can Alter the Resting

question 42

Essay

Changes in ion conductance or ion concentration can alter the resting membrane potential of a cell. For each of the following, write in the letter indicating whether each condition would cause hyperpolarization (H), depolarization (D), or very little change (LC) in the resting membrane potential, and the reason for this change. $\begin{array}{lll}\text { Condition } & \begin{array}{l}\text { Membrane } \\\text { potential } \\\text { change }\end{array} & \text { Reason } \\\text { ncrease in }\left[\mathrm{K}^{+}\right]_{0} &\text{ ----------- } &\text{ ----------- } \\\text { increase in }\left[\mathrm{Na}^{+}\right]_{0} & \text{ ----------- }& \text{ ----------- }\\\text { increase in } \mathrm{K}^{+} \text {permeability } & \text{ ----------- } & \text{ ----------- }\\\text { increase in } \mathrm{Na}^{+} \text {permeability } & \text{ ----------- } & \text{ ----------- }\\\end{array}$
