Q. How does facilitated diffusion present resemblance with enzymatic chemical reactions?
One of the main examples of facilitated transport is the entry of glucose from the blood into cells. Glucose from blood binds to specific permeases hexose-transporting permeases present in the cell membrane moreover by diffusion facilitated by these proteins it enters the cell to play its metabolic functions.
Facilitated diffusion look like chemical catalysis because the transported substances bind to permeases like substrates bind to enzymes and as well, after one transport job is concluded; the permease is not consumed and can perform other succeeding transports.
