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.
In liver cells the smooth ER contains enzymes for the detoxification of harmful drugs and metabolic by-products. In the reproductive organs, smooth ER in the cells produces the steroid hormones testosterone and estrogen.xamples of protein synthesis by the rough endoplasmic reticulum are the proteins produced in secretory cells. These include the digestive enzymes produced in the stomach and the protein hormones like insulin produced in the pancreas.
