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 process by which cells absorb metabolites, hormones, proteins – and in some cases, viruses – by the inward budding of the plasma membrane (invagination).
-
These substances bind to specific receptors on the surface of the cell.
-
Once the substance is bound to the receptor, it triggers the cell to draw the substance in through the cell membrane, forming a vesicle.
-
The vesicle then detaches from the cell membrane and moves into the cell, where the substance can be released and used by the cell.
This process allows the cell to acquire large quantities of a specific substance, even if that substance is not very concentrated outside the cell.
