Endocytosis, Mitochondria, Chloroplasts, Cytoskeleton & ECM

Question 1

Exocytosis

Answer 1

The process by which material is exported out of the cell

Question 2

Endocytosis

Answer 2

Material can be ‘taken into’ a cell

Question 3

What does the plasma membrane surround?

Answer 3

Material outside the cell, trapping it in an endocytic vesicle

Question 4

The endocytic vesicle will fuse with a _______.

Answer 4

Lysosome

Question 5

Lysosome

Answer 5

Membrane blind vesicles that contain digestive enzymes

Question 6

What do primary lysosomes fuse with to form a secondary vesicle?

Answer 6

Endocytic vesicle or a cellular organelle

Question 7

What does TB Bacteria prevent?

Answer 7

The fusion of the endocytic vesicle and primary lysosome

3. Helps mobile cells move

Question 19

Extracellular Matrix (ECM)

Answer 19

A network of multiple types of proteins outside of cells

Question 20

Functions of ECM

Answer 20

1. Provides structural support outside of cells
2. “Glues” cells into higher order structures (organs)
3. Has a role in cell-cell communication
