C2 Endo + Exo

Question 1

Endocytosis

Answer 1

Vesicle forms around particle (too big for carrier proteins) from cell membrane and pinches off so particle is inside cell

Question 2

Endocytosis (pinocytosis)

Answer 2

Active transport + collects fluids and dissolved small molecules, the membrane folds inwards to collect the particles into the cell

Question 3

Endocytosis (receptor mediated)

Answer 3

Active transport + collects proteins, viruses (cannot leave or enter animal cells) and hormones. Vesicles include sacks with sensors to bring particle into the cell

Question 4

Exocytosis

Answer 4

Opposite of Endocytosis (Phagocytosis)
Brings large particles out the cell

Question 5

Is Endocytosis and Exocytosis active or passive?

Answer 5

Active
