Q. Which of the following affect the transport of molecules when carrier mediated facilitated diffusion is involved?
A) Solubility of molecule in lipids
B) Concentration gradient
C) Availability of carrier molecule
D) All of the above
Explanation
In facilitated diffusion, the rate of diffusion is affected by the solubility of molecules in lipids, concentration gradients, molecular size of the molecules, etc. Availability of carrier molecules also affects the rate of diffusion in facilitated transport
