List and describe the three main types of cytoskeleton. If you wanted to do immunocytochemistry to specifically stain each type of cytoskeleton, what is a protein that could be used for each cytoskeletal type (in other words, what is a unique protein for each cytoskeletal type)?
What are three types of actin structures? Describe the involvement of actin structures in cell migration.
How is the growth and shrinking of microtubules regulated? Then describe the roles of microtubules in: chromosomal separation during mitosis and the movement of organelles and vesicles within a cell.
Describe a possible mechanism on how signaling pathways might impact the cytoskeleton, so that cell migration could be regulated in a localized manner within a multicellular organism. (hint: think about the possible transcriptional regulation of the G-protein regulators)
What are 2 main challenges of protein targeting? Then describe one way these challenges are overcome during signal-based targeting and one way…
What are components of the fluid mosaic model of the cell membrane?
A. The cell membrane is a lipid bilayer with molecules such as cholesterol and proteins embedded in it.
B. The lipid bilayer is a solid structure held together by chemical bonds.
C. The cell membrane is a lipid bilayer with no other molecules embedded in it.

- Answer the Guide Question: a) Each cell in an organism has all of the basic parts. Each has a function that benefits the other cells, how might the presence of different cell structures in plant and animal help them perform their functions as an organism. Explain. b) Why is the cell membrane considered as the guard of the cell? c) Why is the lysosome considered as the suicide bag of the cell?arrow_forwardWhich of the following is NOT an example of microtubule-based motility? A. ciliary movement B.contractile ring of cleavage furrow C. pigment granule transport in fish scales D.axonal transport in neurons QUESTION 33 You are studying the role of microtubules and microfilaments in cell motility. You treat fibroblasts with cytochalasin, which inhibits microfilaments, or colchicine, which inhibits microtubules, and observe the following: In controls, the cells migrate in a directed way, elongating as they go. With cytochalasin treatment, the cells completely stop migrating while with colchicine treatment, the cells attempt to migrate in several directions at once. The best conclusion for this is: A Cytochalasin prevents cell migration and colchicine prevents directed cell migration. B. Microfilaments are necessary for cell migration and microtubules are necessary for directionality of migration. C. Microfilaments are necessary for cell migration and microtubules are sufficient for…arrow_forwardIf you think about polymerization like a chemical reaction at equilibrium, how would the concentration of tubulin heterodimers influence the likelihood of microtubule growth versus shrinkage? Select all that apply. Once a monomer is added to a microtubule, its loss from the microtubule is favorable when the monomer concentration is below the critical concentration. Once a monomer is added to a microtubule, its loss from the microtubule is highly unfavorable under most circumstances. Once a monomer is added to a microtubule, its loss from the microtubule depends on the monomer concentration. Once a monomer is added to a microtubule, its loss is highly favorable under most circumstances. Submit Request Answer O Oarrow_forward
