D)ATP production
E)membrane thickness

Quizplus · Accepted Answer

Charged particles are influenced by the electrical gradient, which is established by the distribution of charged ions on either side of the membrane. The concentration gradient refers to the difference in concentration of a substance between two regions, and does not directly affect the movement of charged particles. The size of the particle, pore size, ATP production, and membrane thickness may indirectly affect transport across the membrane, but they are not the primary factor influencing charged particles.
