A client with a diagnosis of type 1 diabetes has begun receiving subcutaneous injections of insulin. The nurse knows that insulin allows glucose to enter the body's cells. This is an example of what transport mechanism?
A) Filtration
B) Passive diffusion
C) Facilitated diffusion
D) Active transport
C
Feedback:
Facilitated diffusion is the process in which certain dissolved substances require the assistance of a carrier molecule to pass from one side of a semipermeable membrane to the other. An example is the role that insulin plays in transporting glucose into cells. Filtration involves the movement of water and passive diffusion is dependent on a concentration gradient. Active transport requires an energy source, something which is not the case with insulin and glucose.
