Which of the following would increase the maximum rate of facilitated diffusion?

Question

Quizplus · Accepted Answer

Facilitated diffusion follows a saturation curve, meaning that once all of the transporters are occupied by the molecule being transported, increasing the concentration gradient will not increase the rate of diffusion. Therefore, increasing the concentration gradient of the transported molecule to the saturation point is the only option that would increase the maximum rate of facilitated diffusion. Choice B of decreasing the concentration gradient would decrease the rate of diffusion. Choice C of increasing the concentration of competitive molecules would compete with the molecule being transported and decrease the rate of diffusion. Choice D of increasing ATP synthesis has no direct effect on facilitated diffusion as it is a passive process.
