Question

Which of the following processes can be either specific or nonspecific depending upon the particular molecules that are transported

a) Active transport
b) Passive transport
c) Simple diffusion
d) Facilitated diffusion

Answer 1

Facilitated diffusion can be either specific or nonspecific depending on the molecules involved.

Step-by-step explanation:

In the context of cell transport, both specific and nonspecific processes can be observed in facilitated diffusion. Facilitated diffusion is the spontaneous passage of molecules or ions across membranes through specific transmembrane proteins. These proteins recognize and bind specific solutes for transport. The specificity of facilitated diffusion lies in integral membrane proteins that determine which molecules are transported, making it capable of being both specific and nonspecific depending on the molecules involved.
