lets work on this problem

19. Growth factor receptors on the cell surface, such as EGF-R, receive signals that promote cell growth and division. To limit this signaling pathway, EGF-R is removed from the cell surface through endocytosis, followed by degradation by the lysosome. Which of the following describes the best experiment to test if EGF-R enters the cell through the clathrin-dependent endocytic pathway? Note: EGF: epidermal growth factor, EGF-R: receptor for EGF a. Knockout EGF-R and test effects on EGF-R signaling b. Prevent lysosomal acidification and measure EGF-R signaling c. Prevent endosomal acidification and measure EGF-R signaling d. Disrupt the function of the AP-2 adaptor and measure EGF-R signaling e. Disrupt the function of the AP-2 adaptor and measure the localization of EGF-R
