Cytosis And Exocytosis

Question 1

What is cytosine.

Answer 1

Active transport where parts of the plasma membrane form unfolding a or out folding. It can lead to transporting materials into a cell (endocytosis) or out of a cell (exocytosis).

Question 2

Question 3

What are the uses of endocytosis ?

Answer 3

Phagocytes use endocytosis to ingest and digest bacterial and dead cells.
Cholesterol is take in through endocytosis.

Question 4

How does exocytosis occur ?

Answer 4

Vesicles containing substances for secretion are pinched off the Golgi apparatus and move towards the cell membrane. The vesicles fuses with the membrane and releases the substances outside the cell or membrane proteins are inserted directly into the bilayer.

Question 5

What are the uses of exocytosis.

Answer 5

Enzymes and antibodies are removed by exocytosis.
