A steroid hormone cortisol is a very hydrophobic substance that enters the cell by the process of simple diffusion. What conditions increase to the speed of transport of cortisol into the cells?

Question

Quizplus · Accepted Answer

Higher temperature increases the speed of diffusion by increasing the kinetic energy of the molecules, including cortisol. This allows cortisol to cross the cell membrane more quickly. Lower temperature, on the other hand, would decrease the speed of diffusion. Lower membrane fluidity and more proteins in the membrane would both hinder the movement of cortisol into the cell, so they are not the best choices.
