Cell Membrane Transport: Endocytosis and Exocytosis

Flashcards covering endocytosis and exocytosis concepts described in the notes.

What is endocytosis?

The process by which cells take in material from outside the cell by forming vesicles from the plasma membrane.

plasma membrane

What is exocytosis?

The process by which materials inside the cell are released to the outside by vesicles fusing with the plasma membrane.

Exocytosis: Fill in the blank: Exocytosis involves vesicles fusing with the membrane to release contents outside the cell.

plasma membrane

Where do vesicles originate during endocytosis?

From the plasma membrane, as it buds inward to form vesicles that carry material into the cytoplasm.

Compare endocytosis and exocytosis.

Endocytosis moves material into the cell; exocytosis moves material out of the cell.

Which cellular structure is involved in both endocytosis and exocytosis?

The plasma membrane.

True or False: In exocytosis, vesicles fuse with the plasma membrane to release contents outside the cell.
