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.

If cells are treated with colchicine, a drug that promotes microtubule disassembly, the location of the ER and Golgi both change dramatically. Rather than being spread out quite widely through the cytoplasm, the ER appears to collapse into the area near the nucleus. (Recall that the ER membrane and the outer nuclear envelope are continuous with one another). In contrast, the Golgi stacks disperse from their usually more compact, central location to areas all over the cell. However, if colchicine is removed, and microtubules are allowed to reassemble, both organelles eventually return to their normal distribution in the cells. How do you account for the change in distribution of the ER & Golgi when microtubules are depolymerized? What protein(s), other than tubulins, allow normal cellular organization to be restored once colchicine is removed? (answer should include information to explain both the ER & Golgi)

Researchers tried to explain how vesicular transport occurs in cells by attempting to assemble the transport components. They set up microtubular tracks along which vesicles could be transported, and they added vesicles and motor protein kinesin. Yet, when they put everything together, there was no movement or transport of vesicles. What were they missing? endoplasmic reticulum contractile microfilaments OATP an axon intermediate filaments
