Solution
The type of transport that enables a cell to acquire bulk quantities of specific substances is receptor-mediated endocytosis.
Here's a step-by-step explanation:
-
Receptor-mediated endocytosis is a mode of active transport in which specific molecules are ingested into the cell.
-
The specific substance (ligand) first binds to a receptor on the cell surface.
-
This receptor-ligand complex then migrates to a clathrin-coated pit, which is an area of the cell membrane that has high concentrations of certain proteins.
-
The clathrin-coated pit then invaginates and forms a vesicle inside the cell, bringing the ligand along with it.
-
Once inside the cell, the vesicle loses its clathrin coat and may fuse with other vesicles or organelles, such as endosomes or lysosomes, where the ligand can be released and used by the cell.
-
The receptors are then recycled back to the
