In one form of endocytosis a molecule binds to a specific protein on the cell surface and triggers vesicle formation and endocytosis. What type of transport is this?
A) Receptor-mediated endocytosis
B) Pinocytosis
C) Facilitated diffusion
D) Active exocytosis
Receptor-Mediated Endocytosis
A cellular process in which cells absorb external substances by the inward budding of its membrane, guided by receptors.
Pinocytosis
A form of endocytosis where cells ingest extracellular fluid and its dissolved contents.
Facilitated Diffusion
The process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.

Final Answer :
A
Explanation :
Receptor-mediated endocytosis involves the binding of molecules to specific receptors on the cell surface, which then triggers the formation of vesicles to internalize the molecules. This process is highly selective and efficient for the uptake of specific substances.
