Imagine two proteins that move from the ER to the cis-Golgi.Protein X has a specific target region that binds to a protein inthe membranes of vesicles bound for the cis-Golgi. Protein Y doesnot specifically bind, and passively diffuses into vesicles boundfor the cis-Golgi. Compare the rate of movement of proteins X and Yfrom the ER to the cis-Golgi as a function of the concentrations ofprotein X and Y (a graph will be very helpful).
