In passive transport, how does increasing temperature generally affect the rate of diffusion across a membrane?
A
It decreases because membrane pores close at higher temperatures.
B
It stops once temperature rises above the freezing point of water.
C
It has no effect because diffusion depends only on the concentration gradient.
D
It increases because molecules have greater kinetic energy and move faster.
