In a nondividing cell such as a liver cell, why must the flow of membrane between compartments be balanced, so that the retrieval pathways match the outward flow? Would you expect the same balanced flow in a gut epithelial cell, which is actively dividing?
Clathrin-coated vesicles bud from eukaryotic plasma membrane fragments when adaptins, clathrin, and dynamin-GTP are added. What would you expect to observe if the following modifications were made to the experiment? Explain your answer.
A. Adaptins were omitted.
B. Clathrin was omitted.
C. Dynamin was omitted.
D. Prokaryotic membrane fragments were used.
