Question
Both the concentration gradient and the electrical gradient affect the diffusion of __________ across membranes.Group of answer choiceswaterproteinsionslipidsATP
Solution
The answer is ions. Both the concentration gradient and the electrical gradient affect the diffusion of ions across membranes. The concentration gradient refers to the difference in concentration of ions on either side of the membrane, which drives diffusion from areas of high concentration to areas of low concentration. The electrical gradient refers to the difference in electrical charge on either side of the membrane, which also influences the movement of ions. Ions will move towards areas of opposite charge.
