People invariably make the same sets of mistakes when they first start shooting video: 1  Trees or telephone poles sticking out of the back of someoneâs head. 2  Interview subjects who are just darkened blurs because there was bright light in the background. 3  Boring shots of buildings with no action.
Best Answer: Protein synthesis (and therefore enzyme synthesis) occurs at the ribosome, and the presence of ribosomes on the ER is what makes it the ROUGH endoplasmic reticulum. The rough endoplasmic reticulum would be the part producing the protein enzymes.
There are two basic types of ER. Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Protein molecules are synthesized and collected in the cisternal space/ lumen. When enough proteins have been synthesized, they collect and are pinched off in vesicles.
