Question 1

What do actin filaments work with?

Answer 1

Myosin motors and actin binding proteins

Question 2

What do actin filaments do in non muscle cells?

Answer 2

Cytokinesis, phagocytosis, cytoplasmic streaming,

Question 3

What does cell locomotion do?

Answer 3

Tissue/organ/cell development, angiogenesis, metastasis, wound healing, immunity

Question 4

What subunit action do cells use to move?

Answer 4

Actin polymerization

Question 5

How do lamellipodium work?

Answer 5

Actin polymerization, move through treadmilling

Question 6

How do WBCs respond to chemical signals?

Answer 6

Cells receive signal, polymerization of actin (caused by arp 2/3 binding to atp actin monomer onto free ends of growing filaments causes cell to become polarized and moves it toward stimulus by pushing the membrane out towards it (treadmilling happens

Question 7

What pushes the cell out?

Answer 7

Actin

Question 8

What pulls the rest of the cell with it?

Answer 8

Myosin

Question 9

How do microtubules help with cell motility?

Answer 9

Fill axon and central domain, support the thin elongating axon

Question 10

What do growth cones do?

Answer 10

Elongate axons

Question 11

How do cells change shape during embryonic development?

Answer 11

Outer cells elongate and form a plate towards end of gastrulation. Cells constrict inwarrd, making a bracket shape bc microfilaments in apical cell region contract inward, then make hollow tube
