### Understanding Ion Permeability and Equilibrium Potentials in Cells Consider the two cells below, where cell #1 is permeable only to the cation \( A^+ \) while cell #2 is permeable only to the anion \( B^- \). #### Diagram Explanation: - **Cell #1** - The permeability allows the cation \( A^+ \) to move freely. - The equilibrium potential for \( A^+ \) shows a negative value, indicating that the inside of the cell is more negative relative to the outside. - Denoted as \( E_{A^+} = - \) - **Cell #2** - The permeability allows the anion \( B^- \) to move freely. - The equilibrium potential for \( B^- \) shows a positive value, indicating that the inside of the cell is more positive relative to the outside. - Denoted as \( E_{B^-} = + \) #### Question: The equilibrium potential for \( A^+ \) in cell #1 is a negative value, while the equilibrium potential for \( B^- \) in cell #2 is a positive value. At the equilibrium potential, what are the concentration gradients for \( A^+ \) and \( B^- \) in cells #1 and 2? #### Answer Choices: 1. \( A^+ \) has a higher concentration outside than inside cell #1 while \( B^- \) has a higher concentration inside than outside cell #2. 2. At the equilibrium potential, cells 1 and 2 cannot have equilibrium potential values opposite to the charge of ions \( A^+ \) and \( B^- \). 3. Both \( A^+ \) and \( B^- \) have higher concentrations outside than inside their cells. 4. Both \( A^+ \) and \( B^- \) have higher concentrations inside than outside their cells. 5. \( A^+ \) has a higher concentration inside than outside cell #1 while \( B^- \) has a higher concentration outside than inside cell #2. Select the correct answer to understand the relationship between ion concentration gradients and equilibrium potentials. --- This educational content provides a basis for understanding how ion permeability and equilibrium potentials function in cellular environments. By analyzing the concentration gradients, one can determine the behavior of ions across cell membranes at equilibrium states.
