Question

(6). To the right is a diagram of a segment of a red blood cell membrane. A. Which protein(s) is/are peripheral proteins? B. Which protein(s) is/are integral transmembrane proteins? C. You are interested in studying the mobility of band 3 protein (shown in red & pink) and assess it using FRAP. Draw the graph obtained from such an experiment (time on the x axis, fluorescence on the Y axis). Explain your results. D. Describe the sorting pathway, starting at a free ribosome, that glycophorin, a glycosylated protein, follows to end up at its final destination in the cell. Include in your answer how and where it becomes glycosylated. glycophorin lipid bilayer band 3 4.2 ankyrin 2.1 4.1 actin ?-spectrin ?-spectrin
