3.25 in. x 4 in. Lantern Slides and These studies showed that the rate of protein synthesis, rate of drainage of the RER to the Golgi and the overall transit rate over the secretory pathway was not accelerated by prior secretagogue release of all preformed zymogen granules. Furthermore, secretory proteins were not rerouted into the cytosol as had been proposed by others.

3.25 in. x 4 in. Lantern Slides, Original Magnification: x16,000, and Protein synthesis is not required for any step in the secretory pathway beyond initial synthesis of exportable proteins. ATP is need for RER to Golgi transport, not for concentration, but is required for stimulated exocytosis.
