A molecule is present at two different concentrations on either side of a membrane.The molecule will have the greatest diffusion rate if the concentration is _______ $\mu$M on one side and _______ $\mu$M on the other.
A) 10; 20
B) 20; 30
C) 50; 60
D) 30; 30
E) 15; 50

Question

Quizplus · Accepted Answer

The greatest diffusion rate occurs with the largest concentration gradient, which is the difference between the two concentrations. Choice E (15; 50) presents the largest difference (35), leading to the highest diffusion rate.
