Transport through pores in cell members is?

Transport through pores in cell members
is ?
a) Active transpert
b) Transcytosis
c) Diffusion
d) Endocytosis

Correct Answer - C
Ans. C. Diffusion
[Ref: Guytonp.49]
Substances can move by simple diffusion directly along the pores
and channels from one side of the membrane to the other.
Thus, simple diffusion can occur by two pathways.

  1. Through membrane lipid bilayer → for lipid soluble substances.
  2. Through pores (water channel) -+ for ions/electrolytes
