if you visualize the cytoskeleton of a cell that is expanding in one direction, you typically observed a strong orientation of the cytoskeleton. Please answer the following three questions. a. Would the cytoskeleton be oriented parallel or perpendicular to the direction of cell expansion? b. Would the cellulose fibers in the cell wall be parallel or perpendicular to the cytoskeleton? c. Explain why cytoskeleton, cellulose fibers, and direction of cell expansion have the relationship mentioned in a and b

(a) If you were to magnify a cell 10,000-fold (typical of the magnification achievedusing an electron microscope), how big would it appear? Assume you are viewing a“typical” eukaryotic cell with a cellular diameter of 50 μm.(b) If this cell were a muscle cell (myocyte), how many molecules of actin could ithold? Assume the cell is spherical and no other cellular components are present; actinmolecules are spherical, with a diameter of 3.6 nm. (c) If this were a liver cell (hepatocyte) of the same dimensions, how manymitochondria could it hold? Assume the cell is spherical; no other cellular components arepresent; and the mitochondria are spherical, with a diameter of 1.5 μm
Which electron or light microscopy technique would you use for the following? (also explain) For visualizing the fine structure of cellular organelles and cell architecture in the cell interior using very thin cross-sections made in Epon. To obtain sequential images of a macromolecule in order to study its activity in real-time. To obtain an extremely clear three-dimensional image of the nucleus of a single cell. What is the magnification of the image in a microscope using a 20x ocular and a 100x objective?
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…
Cell structure and tissue organization is mainly determined by the arrangements of the three cytoskeletal elements. Briefly describe (with the aid of diagrams) the structural arrangements and functions of the three cytoskeletal elements in the following cells. a . a dividing cell b. a moving cell c. a nerve cell asap please.
After investigation of a specimen under light microscope and electron microscope, numerous amounts of spherical shaped particles were seen in the electron microscope while this type of structure was not visible under the light microscope. Further characterization revealed that these particles lack cellular organelles (like the nucleus, mitochondria…). Considering the above circumstance, answer the following questions. (A) What do you think would be the size of the specimen? (B) What do you suspect these particles are most likely to be? (C) Would you define these particles as living? Why/why not-justify your answer briefly
The Size of Cells and Their Components: a. (a) If you were to magnify a cell 10,000 fold (typical of the magnification achieved using an electron microscope), how big would it appear? Assume you are viewing a "typical" eukaryotic cell with a cellular diameter of 50 um.
Each of the following conditions involves a disorder in the function of an organelle or other cell structure. In each case, identify the organelle or structure involved and indicate whether it is likely to be underactive or active. Give brief a brief explanation each. a. A man suddenly felt weak and manifested cyanide poisoning symptoms after ingesting undercooked cassava which contains cyan glycosides. b. A young man learns that he is infertile because his sperm are non-motile. A maize plant is unable to survive due to recessive lethal gene causing albinism. d. An infant is placed on a low phenylalanine diet as his newborn screening results revealed that he inherited phenylketonuria. e. A man develops pleiomorphic liposarcoma (a rare type of cancer) and is told that the cause of the problem is a hard mass of cells in his right inner thigh that rapidly increased in size in a C. matter of two months.
give 3 function of the cell membrane and (a) tell which component of the cell membrane enable it to perform this function? (each of the 3 function) (b) tell how do these components help the cell membrane in performing this function? (each of the 3 function). plsssssss help me answer this question, thank you.
please choose correct letter and explain a bit 1. The strongest way by which a protein can maintain its shape is by using:a) ionic bonds b) disulfide bonds c) star war forces d) van der Waals forces 2. If a cell (like an amoeba) would be capable of migrating from one place to another only with movement created from the inside of the cell, then we can say that that movement is done mainly by: a) glycoproteins b) feet c) microtubules d) actin filaments True or False: In eukaryotic cells (such as human cells), the variety and diversity of proteins is much less than the variety and diversity of lipids.
Below are three statements - two of which are truths and one is a lie. Which of the following statements is a lie? Select one: a. Keratin - an intermediate filament, is classified as Types I and II or acid and base keratins. b. Microfilaments have two structures called bundles and networks. The former is used for movement inside the cell while the latter is for intercellular communication. c. Kinesin is a microtubule motor protein that helps in the transportation of cellular material essential to cell function and moves towards the minus end motor. Clear my choice
You are studying actin polymerization in the lab. You have Tube 1 with cell extract and ATP, and Tube 2 with cell extract and non- hydrolyzable ATP. Assuming both ATP and non-hydrolyzable ATP bind actin monomers with similar affinities, which of the following would observe in the two tubes? Select all that apply The average length of an actin filament in Tube 1 is longer than the average length of an actin filament in Tube 2 The average length of an actin filament in Tube 2 is longer than the average length of an actin filament in Tube 1 Polymerization of actin filaments is inhibited in presence of non-hydrolyzable АТР Depolymerization of actin filaments is inhibited in presence of non-hydrolyzable АТР
