5.5: Bulk transport across the plasma membrane occurse by exocytosis and endocytosis

Question 1

how are large/large amounts of molecules able to get in

Answer 1

large molecules are moved in and out of the cell by exo/endo cytosis

Question 2

Exocytosis

Answer 2

vesicles(membrane bounded protein from ER) from inside fuse with plasma membrane and expel their contents outside the cell

Question 3

Endocytosis

Answer 3

the process of bringing contents ino the cell by forming new vesicles on surface., removes portions of membranes to make room to add the larger molecules

Question 4

3 types of endocytosis

Answer 4

Phagocytosis, Pinocytosis, and Receptor-Mediated Endocytosis, all use ATP

Question 5

Phagocytosis

Answer 5

cell wraps a pseudipodia around a particle and brings it in(white blood cells)(solid)

Question 6

Pinocytosis

Answer 6

cell takes in a small drop of outside fluid in a vesicle to take in large amounts of molecules(liquid)

Question 7

Receptor-Mediated Endocytosis

Answer 7

a substance binds to specific receptors on the cell’s surface, this causes vesciles to form and brings in the specific molecule, what happens to animals cells,not bulk transport
