Adherens junctions link together adjacent cells in an epithelial sheet through the lateral associations of numerous cadherin molecules. On their cytosolic surfaces these junctions are tied to the actin networks of the neighboring cells (see the figure), giving them the remarkable ability to sense mechanical stresses and generate biochemical signals that lead to an appropriate response. Each of the following statements accurately describes a property of this process of mechanotransduction EXCEPT: plasma membrane p120-catenin B-catenin a-catenin actin filaments cadherin vinculin CYTOSOL Choose one: ⒸA. Inhibition of myosin leads to a compensating increase in the size of an adherens junction. OB. Adherens junctions respond to mechanical stress by balancing the forces on adjacent cells. ⒸC. Adherens junctions sense tension and change behavior in response to mechanical stresses. OD. Artificially increased contractile stress in a cell increases the size of an adherens junction.

Analogs of hemidesmosomes are the focal contact sites, which are also sites where the cell attaches to the extracellular matrix. These junctions are prevalent in fibroblasts but largely absent in epithelial cells. on the other hand, hemidesmosomes are prevalent in epithelial cells but absent in fibroblasts. In focal contact sites, intracellular connections are made to actin filaments, whereas in hemidesmosomes connections are made to intermediate filaments. Why do you suppose these two different cell types attach differently to the extracellular matrix?
Although purified actin can assemble reversibly in vitro, various actin-binding proteins regulate the assembly of actin filaments in the cell. Predict the effect on a cell’s actin cytoskeleton if function-blocking antibodies against each of the following were independently microinjected into cells: profilin, thymosin-β4, CapZ, and the Arp2/3 complex.
HC CH reaction with HC CH lysosome CH CH HC CH3 HC CH3 HC CH HC. CH CH3 CH3 ОН OH inside the cell, propranolol sometimes encounters lysosomes, which alter its NH group as shown above (right). reacting with the lysosomes, propranolol becomes trapped inside the cell and can cause psoriasis or other inflammatory side effects. Use IMFS to explain why the altered propranolol gets trapped. T
Amoeboid cells that migrate through our tissues, such as the class of white blood cells known as neutrophils, often do so in a directed manner, triggered, for instance, by chemical signals released by pathogens such as bacteria. Directed migration in response to a chemical stimulus is known as chemotaxis. Part of an efficient chemotactic response is the ability of cells to polarize. As is the case with our structurally-polar polymers like F-actin or microtubules, polarization here refers to an asymmetry in the cells, rather than an electrical charge. In this case, it involves one part of the cell becoming the “front” (or leading edge) and another the rear. In a well-polarized, migrating cell, it’s been observed that an active form of Rac (which, in turn, can activate ARP 2/3) is concentrated towards the front of the cell, whereas an active form of Rho (which, in turn, can activate formin, inhibit ADP, and activate myosin II) is found toward the rear of the cell. Based on your…
Gap junctions and tunneling nanotubes are two distinct types of direct intracellular communication. In comparing and contrasting gap junctions and tunneling nanotubes, which of the following statements is true? gap junctions provide a portal for small molecules, proteins and small organelles to move from cell to cell, tunneling nanotubes only permit small molecules to pass between cells typically, there are only two gap junctions that exist between adjacent cells that are communicating via this mechanism; on the other hand, there are many tunneling nanotubes between communicating cells both gap junctions and tunneling nanotubes can pass small molecules between cells none of the above is true

The electrochemical gradient across the plasma membrane is important for cellular functions including protein transport and information transfer. Pinpoint the specific protein and explain how it maintains the electrochemical gradient.
Our current experimental procedure works because Con A adheres strongly to the nitrocellulose membrane while HRP hardly binds to the membrane at all. If HRP binds as strongly to the membrane as Con A does, our current scheme will not work. Assuming that's the case (HRP strongly binds to the membrane non-specifically, regardless of the presence of ConA), you will need to treat the membrane with an additional solution before treating it with HRP. What solution would that be? O Saturated NaCI solution. O Concentrated HCI. A membrane-binding protein. Concentrated glucose slution.
Phagocytosis of a bacterial cell by a macrophage, involves extensive remodeling of the actin microfilaments in the cell cortex to produce extensions of the plasma membrane and formation the phagocytic cup. Based on your knowledge of microfilament assembly/disassembly and related cell membrane deformation, explain the underlying processes that would be involved in formation of the phagocytic cup.
Cells transporting substances across their membranes is essential. Choose TWO of the following types of cellular transport. ๏osmosis ๏active transport (b)Using the same transport types, identify a specific cell that utilizes that type of transit (i.e. one cell for each transport type, or two different cell examples), and detail a substance that is transferred. (c)A typical human lymphocyte has a radius of about 10 μm, while a typical bacterium (e.g., S. pneumoniae) has a radius of about 1 μm. Assuming that both cell types are perfectly spherical, compare and contrastthe transport mechanisms for each of these cells.
