question 109

Multiple Choice

• A)The concentration of Na⁺ in A will be higher than it was at time zero.
• B)Diffusion of K⁺ from A to B will be greater than the diffusion of K⁺ from B to A.
• C)There will be a potential difference across the membrane,with side B negative relative to side A.
• D)The electrical potential difference and diffusion potential due to the concentration gradient for K⁺ will be equal in magnitude and opposite in direction.
• E)The concentration of Cl⁻ will be higher in B than it was at time zero.
