Question

6. Which type of endocytosis involves ligands? What does this type of transport enable a cell to do?

Answer 1

In receptor-mediated endocytosis, specific molecules act as ligands when they bind to receptors on the plasma membrane. The cell can acquire bulk quantities of those molecules when a coated pit forms a vesicle and carries the bound molecules into the cell.

Answer 2

Answer:

A variety of ligands and macromolecules enter cells by receptor-mediated endocytosis. The cell can gather bulk portions of these molecules while a covered pit forms a vesicle and consists of the certain molecules into the cell.

Explanation:

The routes that lead inward from the cell surface to lysosomes begin with the technique of endocytosis, with the aid of using which cells take in macromolecules, particulate substances, and, in specialized cases, even different cells. In this technique, the fabric to be ingested is gradually enclosed with the aid of using a small part of the plasma membrane, which first invaginates after which pinches off to form an endocytic vesicle containing the ingested substance or particle. Two important kinds of endocytosis are prominent on the idea of the scale of the endocytic vesicles formed. One kind is referred to as phagocytosis (“cellular eating”), which entails the ingestion of massive particles, consisting of microorganisms or useless cells through massive vesicles referred to as phagosomes (generally >250 nm in diameter).
