Introduction:
The virus of polio is responsible for causing paralysis in living organisms. This poliovirus is transmitted through the means of contaminated water or food. It can also be transferred or transmitted with an infected person.

The drug taxol, extracted from the bark of yew trees, has an opposite effect to the drug colchicine, an alkaloid from autumn crocus. Taxol binds tightly to microtubules and stabilizes them; when added to cells, it causes much of the free tubulin to assemble into microtubules. In contrast, colchicine prevents microtubule formation. Taxol is just as pernicious to dividing cells as colchicine, and both are used as anticancer drugs. based on your knowledge of microtubule dynamics, suggest why both drugs are toxic to dividing cells despite their opposite actions.

- Fibroblasts are motile cells that “creep” about in the connective tissue of the body where they play a number of roles, including secretion of the extracellular matrix and initiating certain wound healing events. These cells do not usually have microvilli nor do they express the actin-binding protein villin; both of these properties are characteristic of certain epithelial cells, such as those lining the intestine and kidneys. Remarkably enough, however, if one artificially engineers fibroblast cells to produce the villin protein, microvilli form on the fibroblasts. Given what you know about the function of villin, why might this striking change in cell morphology occur?arrow_forwardSelect the best answer or answers from the choices given: A physiologist observes that the concentration of sodium inside a cell is decidedly lower than that outside the cell. Sodium diffuses easily across the plasma membrane of such cells when they are dead, but not when they are alive. What cellular function that is lacking in dead cells explains the difference? (a) osmosis, (b) diffusion, (c) active transport (solute pumping), (d) dialysis.arrow_forwardWhat is the function of the abundant endoplasmic reticulum in plasma cells?

He was diagnosed as having cholera, a disease transmitted through unsanitary water supplies contaminated by fecal material from infected indiv iduals. The toxin produced by cholera bacteria causes Cl- channels in the lurninal membranes of the intestinal cells to stay open, thereby increasing the secretion of Cl- from the cells into the intestinal tract lumen. By what mechanisms would Na+ and water be secreted into the lumen in conjunction with Cl- secretion? How does this secretory response account for the severe diarrhea that is characteristic of cholera?arrow_forward"Sodium is usually more concentrated outside the cell than inside.

- Nitric oxide (NO) is a gaseous molecule with lipid solubility similar to that of O2 and CO2. Endothelial cells lining arteries use NO to signal surrounding smooth muscle cells to relax, thereby increasing blood flow. What mechanism or mechanisms would transport NO from where it is produced in the cytoplasm of an endothelial cell into the cytoplasm of a smooth muscle cell, where it acts?arrow_forwardSecretory vesicles fuse with the cell membrane to release their contents to the outside of the cell. In this process, the membrane of the secretory vesicle becomes part of the cell membrane because small pieces of the membrane are continually added to the cell membrane, one would expect the cell membrane to become larger and larger as secretion continues. The cell membrane stays the same size, however. Explain how this happens.arrow_forwardWhich of these answers explains why synaptic vesicles only releasee their neurotransmitter cargo in response to a signal? A) the necessary Rab proteins are not synthesized until an action potential arrives B) vesicle formation at the trans-Golgi network cannot occur in the absence of plasma membrane depolarization C) an additional protein, synaptotagmin, makes vesicle fusion dependent on the calcium concentration D)a plasma membrane transporter is needed to actively pump neurotransmitter into the synaptic cleft. These are inactive until membrane depolarizationarrow_forward
