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 substances have bound to these receptors, the plasma membrane invaginates, forming a vesicle containing the substances.
-
This vesicle then detaches from the plasma membrane and moves into the cell, where it merges with other vesicles and releases its contents for use within the cell.
-
This process allows the cell to acquire bulk quantities of specific substances that may be present in low concentrations in the extracellular fluid.
