Biology CB16 Quiz Endocytosis & Exocytosis

Endocytosis and exocytosis are examples of vesicle transport.

• true

• false

Endocytosis and exocytosis are examples of passive transport

• true

• false

________________ is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane.

• Endocytosis

• Exocytosis

• Isocytosis

• Kinicytosis

Pinocytosis or cellular eating, occurs when the dissolved materials enter the cell. The plasma membrane engulfs the solid material, forming a phagocytic vesicle.

• true

• false

Phagocytosis, or cellular drinking, occurs when the plasma membrane folds inward to form a channel allowing dissolved substances to enter the cell.

• true

• false

________________________ describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.

• Endocytosis

• Exocytosis

• Isocytosis

• Kinicytosis

Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin.

• true

• false

During exoocytosis a membrane folds over the substance and it becomes completely enclosed by the membrane. At this point a membrane-bound sac, or vesicle, pinches off and moves the substance into the cytosol.

• true

• false

An example of endocytosis would be a liver cell making a vesicle to place toxic compounds in and remove them from the cell. 

• true

• false

An example of exocytosis would be cells of the the microvilli absorbing liquid nutrients in the gastrointestinal tract. 

• true

• false
