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:

  1. 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).

  2. These substances bind to specific receptors on the surface of the cell.

  3. Once the substances have bound to these receptors, the plasma membrane invaginates, forming a vesicle containing the substances.

  4. 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.

  5. This process allows the cell to acquire bulk quantities of specific substances that may be present in low concentrations in the extracellular fluid.
