Question

Exocytosis is a type of cellular transport that allows materials to move across the plasma membrane of a cell. Which of the statements describe properties of exocytosis? a. Exocytosis is the primary method of transporting large molecules out of the cell. b. Exocytosis is the primary method of transporting large molecules into the cell c. Exocytosis uses transport vesicles to export materials from the cell d. Exocytosis uses membrane channel proteins to import materials into the cell. e. Exocytosis uses transport vesicles to import materials into the cell.

Answer 1

Answer:

C. Exocytosis uses transport vesicles to export materials from the cell

Explanation:

Exocytosis is the reverse process of endocytosis including the expulsion of the material that is membrane -encapsulated (material is packaged in the vesicles ) inside the cell out of the cell. It has following steps :

1) The cell forms a vesicle around a material which is to be expelled.

2) The vesicle is transported to the cell membrane.

3) The vesicle membrane fuses with the cell membrane and releases the contents from the cell.

Hence option C. Exocytosis uses transport vesicles to export materials from the cell IS THE RIGHT OPTION.

Answer 2

Answer: Option C.

Excytosis uses transport vesicles to export material out of the cell.

Explanation:

Excytosis is process by which the cell transport secretory products and other large molecules from the cytoplasm through to the cell membrane are excreted to the outside environment. The excytosis, membrane bound intracellular vesicles join to the plasma membrane to secrete content and export it out of the cell.
