8. Researchers obtain a pure solution of antibodies that bind specifically to the cadherins (linking proteins) of the desmosomes of epithelial cells of a mouse. As a follow up of their previous experiment, they take a tube of individual muscle cells from a chicken and add antibodies to the tube. What is the predicted outcome of this second experiment? A. The antibodies will bind to the chicken muscle cells, so the cells will adhere to each other B. The antibodies will bind to the chicken muscle cells, so the muscle cells will not adhere to each other C. The antibodies will not bind to the chicken muscle cells, so the cells will adhere to each other D. The antibodies will not bind to the chicken muscle cells, so the cells will not adhere to each other
2. In the images above, use the scale bar to deduce what are you most likely to be looking at. What do you think is being shown in the figure? A. An image of many cells in a tissue. B. A sub-cellular image. C. An image of a whole cell. The location of phosphatidylserine (PS) was visualized in the figure above by a protein called annexin that specifically recognizes and binds to PS. Annexin was injected into a blood vessel in the live embryo at either day E13 (left) or E14 (right). The live embryo was cultured for 30 min before fixing and staining. Annexin can leak out of embryonic blood vessels by leaking between the immature cells. Annexin is labeled in brown. Ignore the arrows..
2. The mannose 6-phosphate receptor is located predominantly in endosomes and the TGN, but about 10% of the mannose 6-phosphate receptor molecules are in the plasma membrane. Suppose you have an antibody that associates with the mannose 6-phosphate receptor and blocks the ability of the receptor to bind mannose 6-phosphate. Suppose further that this association is rapid and effectively irreversible. If you incubate cells with the antibody for a brief time and then wash away excess antibody, the cells continue to sort lysosomal enzymes normally. But if you incubate cells continuously with the antibody for a prolonged time, the cells begin to secrete lysosomal enzymes. a) How would you interpret this result? b) Suppose that the antibody has been fluorescently labeled by covalently attaching a fluorophore. If you examine cells that have been incubated continuously with this labeled antibody, what types of fluorescence patterns would you expect to see at different time points after…

7. Researchers obtain a pure solution of antibodies that bind specifically to the cadherins (linking proteins) of the desmosomes of epithelial cells of a mouse. They then take a culture of these cells, divide it into separate control and experimental tubes, and add antibodies to the experimental tube and an equal volume of water to the control tube. What is the predicted outcome of this experiment? A. Cells in the experimental tube will adhere to each other, but cells in the control tube will not B. Cells in both tubes will adhere to each other C. Cells in neither tube will adhere to each other D. Cells in the control tube will adhere to each other, but cells in the experimental tube will not

C It would affect the cell's ability to attach to the cytoskeleton through adaptor proteins. D It would affect both the cell's ability to attach to other cells and the cell's ability to attach to the cytoskeleton.
