An increase in the extracellular concentration of K⁺ above normal would result in A)A decrease in intracellular K⁺ B)An increase in intracellular K⁺ C)A decrease in intracellular Na⁺ D)An increase in intracellular Na⁺ E)No change in intracellular ion concentrations

Question

Quizplus · Accepted Answer

An increase in extracellular concentration of K⁺ will result in more of these ions being available to enter the cell, leading to an increase in intracellular concentration. This is due to the fact that these ions move through ion channels down their concentration gradient, from an area of higher concentration (extracellular fluid) to an area of lower concentration (intracellular fluid). Therefore, the correct choice is B - An increase in intracellular K⁺.

An Increase in the Extracellular Concentration of K+ Above Normal

An Increase in the Extracellular Concentration of K⁺ Above Normal
