You bleach a very small area (<1%)of the Golgi, and measure fluorescence in that area over time. You normalize the values to the initial fluorescence, and get the graphs below. Giantin is noted by a solid line, and GPP130 by the dashed line. a) Which protein diffuses faster? Giantin (slope is higher) b) Draw the expected trace if all of giantin were mobile.
