Name the type of endocytosis, during which molecules bind to specific proteins embedded in the plasma membrane before they are engulfed by the cell. The molecules that are transported into the cell have a conformation that fits snugly with the protein, to which they attach before they are engulfed.

The receptor-mediated endocytosis.

Explanation:

When particles are moved into a cell by enclosing them in a plasma membrane like vesicle by the different forms of transport, it can be said to be endocytosis process.

The receptor-mediated endocytosis can occur when cell surface receptors ensure the specificity of transport in endocytosis process.

The receptor mediated endocytosis is when molecules bind to specific proteins embedded in the plasma membrane before they are engulfed by the cell. It triggers the assembly of clathrin triskelions by binding extracellular molecules to receptors.

It mainly happens through clathrin coated pits and vesicles.
