The process described is receptor-mediated endocytosis. Here's a step-by-step explanation:

1. The specific molecules outside the cell bind to the receptors on the cell's surface. These receptors are embedded in the cell membrane and have a specific shape that matches the molecule.

2. Once the molecule binds to the receptor, it triggers the cell membrane to invaginate or fold inward, forming a pocket around the molecule.

3. This pocket deepens and eventually pinches off to form a vesicle inside the cell. This vesicle contains the molecule and the receptor.

4. The vesicle is
