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…
Many eukaryotic organelles are involved in the production and shipping of proteins out of the cell. Explain the pathway that a protein takes from its initial instructions through to its exportation from the cell. Include ALL organelles involved and explain their function.
The figure above shows the organization of a protein that will eventually reside in the plasma membrane. The boxes labeled 1 and 2 represent membrane-spanning sequences and the arrow represents a site of action of signal peptidase. Which of the following statements must be TRUE about this protein? O a) Most of this protein will project from the cytosolic side of the membrane. O b) The mature version of this protein will span the membrane twice. c) This is a multi-pass membrane protein. O d) The mature version of this protein will span the membrane once.
Explain why the statement is correct. Which is true of the ribosomes of endoderm cells of the Cnidaria (jellyfish)? They: are attached to the Rough Endoplasmic reticulum (RER) and carry out the synthesis of the primary structure of proteins
Select the most accurate explanation for how vesicular transport occurs when a receptor is moving from the plasma memberane to the late endosome/lysosome. A. Endosomes containing the receptor are transported by myosin II walking towards the minus end of microtubules. Endosomes are targeted to the late endosome/lysosome by Rab and SNARES facilitate membrane fusion. B. Endosomes containing the receptor are transported by myosin V walking towards the minus end of microtubules. Endosomes are targeted to the late endosome/lysosome by Rab and SNARES facilitate membrane fusion. OC. Endosomes containing the receptor are transported by dyenin walking towards the minus end of microtubules. Endosomes are targeted to the late endosome/lysosome by Rab and SNARES facilitate membrane fusion. D. Endosomes containing the receptor are transported by kinesin-13 walking towards the plus end of microtubules. Endosomes are targeted to the late endosome/lysosome by clathrin and SNARES facilitate membrane…
Stathmin is phosphorylated by cyclin dependent kinases in response to extracellular signals such as growth factors. To further understand the role of phosphorylation in stathmin function, you decide to treat cells with growth factors in the presence or absence of phosphatase and observe microtubule dynamics. Based on the known function of stathmin, and phosphorylation of stathmin, how would you expect phosphatase treatment to affect microtubule dynamics? A. Decreased frequency of catastrophe in the presence of phosphatase, compared to untreated control B. Increased frequency of catastrophe in the presence of phosphatase, compared to untreated control C. Rapid microtubule polymerization in the presence of phosphatase, compared to untreated control D. Catastrophe frequency is the same in phosphatase treated and control cells
The LDL receptor is internalized via endocytosis every ten minutes and recycled to the membrane. How does the cell recycle the receptor and not the ligand (in this case LDL)? A. The high pH (~10) of the early endosome causes dissociation of LDL from the receptor and the receptor is segregated into recycling endosomes. B. The low pH (~5) of the early endosome causes dissociation of LDL from the receptor and the receptor is segregated into recycling endosomes. O C. A targeting sequence on the ligand sorts it to the late endosome/lysosome. D. This is an error-prone process, the ligand often gets recycled accidentally.
After pinocytic vesicles fuse with early endosomes, one possible fate of both cargo receptors and their cargo could be translocation to a new plasma membrane location, followed by exocytosis of the cargo molecule, which commonly occurs in human gut epithelial cells carrying which cargo? the human immunodeficiency virus (HIV) the glucose molecule the low density lipoprotein (LDL) the influenza virus the cholesterol molecule
Explain the reason why mitochondria requires a special translocator to import proteins across the outer membrane, when the membrane already has porins.
Discuss the pathway that secretory proteins (proteins destined to leave the cell) take through the endomembrane system starting with their synthesis and ending with their secretion from the cell
IN the figure for D: The organization of a protein that normally resides in the plasma membrane in shown in the figure below. The boxes labeled 1,2 3 and 4 represent membrane-spanning sequences and the arrow represents a site of action of signal peptidase. Given this diagram, which of the following statements must be true? (C) (D) oplasmic Reticulum The N-terminus of this protein is in the ER lumen The mature version of this protein will span the membrane twice, with both the N- and C-terminus in the cytoplasm. Two of the answers are correct The C-terminus of this protein is in the ER lumen
