16. 1. Vesicles transport substances within the cell. Small vesicles containing substances made by the ER are pinched off from the ER. How substances made by the endoplasmic reticulum enter the Golgi apparatus and are finally secreted out of the cell rough endoplasmic reticulum vesicle forming Processes in the Golgi Apparatus

18. 1. Vesicles transport substances within the cell. Small vesicles containing substances made by the ER are pinched off from the ER. 2. Vesicles then fuse with the Golgi apparatus and release their contents into the Golgi apparatus. The substances made by the ER may be modified inside the Golgi apparatus. How substances made by the endoplasmic reticulum enter the Golgi apparatus and are finally secreted out of the cell rough endoplasmic reticulum vesicle forming vesicle fusing with Golgi apparatus Golgi apparatus vesicle pinched off Processes in the Golgi Apparatus
19. 1. Vesicles transport substances within the cell. Small vesicles containing substances made by the ER are pinched off from the ER. 4. Secretory vesicles fuse with the cell surface membrane and their contents are released outside the cell. How substances made by the endoplasmic reticulum enter the Golgi apparatus and are finally secreted out of the cell 3. Secretory vesicles containing these modified substances are pinched off from the Golgi apparatus. They then move to fuse with the cell surface membrane. rough endoplasmic reticulum vesicle forming secretory vesicle pinched off substances released outside the cell secretory vesicle fuses with cell surface membrane Processes in the Golgi Apparatus vesicle pinched off 2. Vesicles then fuse with the Golgi apparatus and release their contents into the Golgi apparatus. The substances made by the ER may be modified inside the Golgi apparatus . vesicle fusing with Golgi apparatus Golgi apparatus
