components of the Golgi membranes may help to clarify their relationship to the 

 other membranous elements of the cytoplasm.

DISCUSSION 



/?. E. Beyer, E. L. Kuff, D. E. Green, G. Rtimney 



Dr. Beyer: Do you see any continuity between the Golgi vesicles and the membrane 

 of the endoplasmic reticulum? If so, do you have any idea of a functional role for the 

 Golgi apparatus in relation to the synthesis of cellular products? 



Dr. Kuff: Yes, continuities between the Golgi membranes and the rough-surfaced 

 membranes of the endoplasmic reticulum (ergastoplasm) ha\e been obserx ed in a num- 

 ber of cell types. Dr. Palade has illustrated this in the case of the pancreas. In our 

 present state of knowledge, there is no convincing evidence that the Golgi membranes 

 are involved in the actual synthesis of cellular products. It would appear more likely 

 that they function in relation to transport of secretory products to and across the cell 

 membranes.
